LAW OF REFLECTION
When a light ray strikes a plane mirror it changes its direction which is known as “reflection”. The light ray, which strikes the mirror, is known as “incident ray” and the ray after reflection is known as “reflected ray”. The perpendicular line which bisects the incident ray and reflected ray is called normal drawn to the point of intersection. The incident ray, reflected and the normal drawn to the point of intersection lie on the same plane. (Fig 1)
When the light reflects in plane mirror the angle of incidence is always equal to the angle of reflection.
Example
When a light ray is directed to a plane mirror from 30’ to the normal, it strikes a point in the other side of it, after reflecting. The angle between the place where light is directed and normal will always be equal to the angle between normal and the point where the light strikes after reflecting.
• Angle of incidence = 30’
• Therefore, angle of reflection = 30’
How do we see the objects in a plane mirror?
We need light to see any object. To see an image of an object in a mirror, you should see in the line of the object. As you sight at the object, light from the object travels to your eye after reflecting in the mirror. The diagram shows that the light reflects off the mirror in such a manner that the angle of incidence is equal to the angle of reflection.
Characteristics of the images formed in a plane mirror
• Virtual
• Laterally inverted
• Equal in size
• Formed at equal distance between the object and the mirror.
REFLECTION IN CURVED MIRRORS
All the light rays follow the reflective laws. We find the image of an object using those reflection laws. The image is the place where two or more rays gets converged at a si...

...ght can enter the camera. Most cameras have functions that allow a person to view the scene to be recorded, allow for a desired part of the scene to be in focus, and to control the exposure so that it is not too bright or too dim. A data display, often a liquid crystal display, permits the user to view settings such as film speed, exposure, and shutter speed.
HOW DO WE GET THE IMAGE IN A CAMERA?
The above diagram shows the functional ray diagram of a camera. The light enters the camera passing two convex or converging lenses. The lenses of the camera is adjusted in a way that the light from the object passes through the pole of the first lens. And the pole of the first lens is the centre of curvature of the second lens. There the light travels in a straight path.
Characteristics of the image formed in a camera
• Real image
• Inverted
• Diminished
Mirrors are first introduced in part one of the novel where Clarisse is describes as a mirror by Montag. Also presented by Granger towards the end of the novel, the mirror is a symbol of the lacking self-reflection but also it cure. Mirrors reflect a perfect image of a person back at them – an image that is neither tarnished nor beautified. Mirror here are a symbol of seeing within one’s soul in pursuit of rebirth, and are a tool to be used in the search what has gone terribly wrong in such an empty society. In a society that lives without living, thinking or feeling like Montag’s looking into a mirror ma spark a thought, and a thought may spark that internal rebellion. Furthermore, metaphorical mirrors are of equal significance when understanding this symbol. Clarisse is Montag’s inner mirror; she reflects the personality and life of Montag back at him, allowing him to learn and question what he sees. Montag is also Faber’s mirror – he reflects Faber’s recent emptiness and his cowardice at not attempting release society from its suffering. Mirrors are a great symbol of self-actualization that leads to rebirth in the novel Fahrenheit

The presence of mirrors is highlighted in this episode. Before this episode there has not been an emphasis on mirrors, even though they appear in other episodes. I feel like the use of this prop is important in understanding the episode. Every time a mirror appears, there is a different circumstance that the character is dealing with. The first mirror appears in Quinn’s house. She is trying on her Chastity Ball dress with her mom, and the dress does not zip up all the way. Quinn is shown in the mirror as the mom measures her stomach. In this instance, the mirror could signify a desire to hide the truth, despite the fact that the truth is there for everyone to see. The second time a mirror is used is in Finn’s basement. He and Kurt are discussing his dad’s bravery in war, while trying on his dad’s old suit jacket. This scene is open on an emotional level, and the mirror works to illustrate that Finn is more like his dad than he realizes. It acts as a reflector for the characteristics that Finn will demonstrate later in the episode and in the series. Finally, a mirror is used with Rachel when she is being told by another student that she does not have a chance with Will. In this scene Rachel is applying makeup in the mirror. The presence of a mirror, and it being actively used, could indicate that Rachel is hiding the truth from herself. Rachel’s character rarely wears a lot of makeup, which emphasizes the use of the mirror. Instead of being honest with herself, Rachel is denying the truth that she is knows is there.
This reflective essay will demonstrate the concept of reflection. The model of reflection by Driscoll, 2007 has been followed in this essay to reflect the clinical skills that I have studied and practiced in week 7to week 9 of this unit which assisted me to get prepared for the practical experience which I will commence at the end of this semester. I have practiced numerous skills during the practicals class, but this essay will be a focus on taking care of bedsore and wound management.
The mirror is another sêma. A mirror shows reflection and this reflection is of the memories that were shared between Chunhyang and Mongryong. A person can reflect on past events and build connections between places, objects, and people. The signs that people give to each other are important for recognition and building relationships. The importance of sêma can be seen in the Odyssey as well.
...mirror revealing the dual natures within her femme fatale, by the intimate conversation she holds with Leonard by confiding in him of her loss in order to gain his trust. Another notable symbolism used in the film is the photographs which Leonard uses to recreate his short term memory. The fact that he is forced to rely on his old memories to survive turn out to be difficult because Leonard can't realize the true meaning of the photos he carries and therefore is not capable of reaching the same ending every time he sees them. In other words, his dependance on the photos to remember only helps him remember an alternate reality. Thus, as seen by Leonard’s dialogue, “We don’t need mirrors to remind ourselves of who we are”, Nolan explains that the deception of one’s memories cannot be justified whether it be for the better good for it can only lead one to harm’s way.

The four main components of the eye that are responsible for producing an image are the cornea, lens, ciliary muscles and retina. Incoming light rays first encounter the cornea. The bulging shape of the cornea causes it to refract light similar to a convex lens. Because of the great difference in optical density between the air and the corneal material and because of the shape of the cornea, most of the refraction to incoming light rays takes place here. Light rays then pass through the pupil, and then onto the lens. A small amount of additional refraction takes place here as the light rays are "fine tuned" so that they focus on the retina.
The first photograph above is one of the many photographs taken by Jack Flange. Jack Flange is a famous photographer particularly specialises in photographing light and surfaces. The scientific value contained in his photograph above will be discussed and hopefully you will be convinced that the photographs taken by Jack is of high standard and the scientific ideas about reflection, transmission and refraction are well demonstrated.
Understanding how our eyes work can be a really interesting thing. Many people don’t realize vision actually begins when light rays are reflected off an object that then enters the eye through the cornea. The cornea is a transparent bulge, in the front of our eyes that allows us to begin refraction. The cornea is one of the most important things in our eyes that allow us to see the things we do. After the reflected light rays enter the cornea, they then p...

. After reflection of the two beams, they recombine at the beam-splitter. Depending on the location of the moving mirror, difference in the optic paths are generated. The two beams interfere constructively and therefore lead to a maximum detector response when they are in phase with each other. The beams interfere destructively when they are out of phase with each other. (14)(15)
Now in order to understand how lights is able to be refracted in different angles, it is important to understand the Snell’s Law which states that, the refractive angle always depend on the refractive index of both media. Now, the refractive index keeps on changing depending on the wavelength of the light passing through. Light, as we know, it is a wave that has different wavelength. Each wavelength represents a different color. Thus, different colors will have different refractive index when passed through the same media. It is important to note that light is normally refracted twice when it travels through a prism, first on its way in, and when it is going back.
