In this universe there are many thing that we cannot explain. Among these many things is light. Light, as far as we know, come in different wavelengths and the size of the wavelength determine what type of light it is. The middle wavelength lights are what gives us the seven basic colors of red, orange, yellow, green, blue, indigo and violet. Beside these visible lights there are the lights that cannot be seen by the human eye. These invisible lights can be grouped into two other groups the long waves and short waves.
The first group of waves is the longer wavelength of light including infrared and radio waves. Radio waves, the longest wavelengths, alternate and can be volatile. Arthur C. Clarke said in the essay "The Light of Common Day" that since radio waves fluctuate so much no animal has ever been able to sense them. He goes on to say that if you had an eye big enough to see radio waves your eyes would be millions of times larger than a normal eye. The next longest wave is the infrared light waves. Infrared light is used nowadays to see in the night. Special goggles are designed to pick up infrared light making it possible to see at night.
The next group of light waves are the shorter waves of ultraviolet and x-rays. Ultraviolet light, sometimes referred to as UV, is right next to violet and is just beyond sight. UV light is what causes sunburns and can be very painful. In Arthur C. Clarks essay it states that even though UV light is not visible the retina of the human eye reacts powerfully to it. He compare the human eye to a camera and says that a good camera need may types of lenses made out of different types of glass to take a good picture. The human eye has only one lens and cannot possible see UV light. The last type of light is the x-ray. The x-ray is the smallest wave and is used in the medical field greatly to take pictures through flesh of bones. Even though x-rays are very useful they can be very dangerous. They have been know to disrupt radio waves and can poison a human body to the point of death.
War was one of the most difficult and brutal things a society could ever go through. World War II was especially terrible because it affected so many people.World War II was centered in Europe and the people of the European countries felt the effects much more than many of the other countries that were also participating in the world war. In the book All the Light We Cannot See written by Anthony Doerr, the story took place during World War II in Europe, the center stage for the war. This war was one of the most difficult wars because it destroyed homes, displaced thousands, tore families apart, killed off loved ones, and forced people to make tough decisions they had to live with for the rest of their lives. In All The Light We Cannot See,
Another speaker, Margaret Livingstone delves into the visual aspect of our senses. Livingstone mentions how artists recognize things about vision that neuroscientists are not privy to until years later. Livingstone discussed the differentiation between color and lightness, and how the two contribute differently to a work of art. Color is thought of as “comparing activity” whereas light is thought of as “summing them.” Livingstone indicates that the visual system is subdivided into a ventral system and a dorsal system. The ventral system is responsible for object recognition, face recognition, and color. The dorsal system is responsible for navigating through the environment, special organization, and emotional recognition. The ability for humans to see distance and depth is carried via our colorblind part of our visual system. As a result, Livingstone concludes that one cannot see depth and shading unless the luminance is right to convey three-dimensional.
“Hope in the face of difficulty. Hope in the face of uncertainty. The audacity of hope! A belief in things not seen. A belief that there are better days ahead.” President Obama’s 2004 keynote speech gives a timeless message of hope that especially resonates with minorities who face an uncertain future. Similarly, in her novel Beloved, Toni Morrison develops the theme that hope in the face of forced dehumanization, through the relationship between darkness and light, gives the oppressed a purpose and the ability to overcome and thrive despite persecution.
All the Light We Cannot See by Anthony Doerr, is a fictional World War II book that uses powerful images to evoke emotions from the reader. The book is staged in many different places throughout Europe, and follows the story of two teenagers, Werner and Marie-Laure. Werner is an albino German orphan, doomed to the life of a coal miner, but when he finds a radio and fixes it his life is completely changed. He goes to an advanced German school where he escapes the miserable life he was once fated to have. Marie-Laure is a blind French girl who lives in Paris until the situation in Germany becomes too strong to ignore. She and her father, the Museum of Natural history's master of locks, flee to a town called Saint-Malo where Marie-Laure becomes a part-time messenger for the French resistance, delivering codes to be played through a secret radio. The book is a fine read for all ages, and readers
Light and sound are similar in some ways too, though. They both have frequencies that humans cannot detect (ultraviolet, infrasonic, etc.). Since both of them are also waves, they can be made to interfere. They can also be made to reflect and refract.
the earth’s atmosphere the moon catches light from the sun and reflects it down to earth. As the moon reflects the sun’s light rays down to earth, those rays of light travel through the earth’s atmosphere in the form of different wavelengths which then produce different colors of visible light. For example when the moon is low in the sky and close to the earth’s horizon, light from the sun has to pass through more of the earth’s atmosphere in comparison to when the moon is high in the sky or positioned directly overhead. When this happens, air molecules filter out short wavelengths of visible light such as green, blue, and purple and scatter’s them throughout the earth’s atmosphere. When the moon is high in the sky...

...in wavelengths of lights that human eye view the rainbow which is formed when light passes through the water droplets in the air. It then changes its path using the principles of refraction and different wavelength lights take a turn on a different angle.
Light is what lets you experience colour. The pigment of the retina in your eyes is sensitive to different lengths of light waves which allows you to see different colours. The wavelengths of light that humans can see are called the visible colour spectrum.
we can’t see in the UV spectrum, and there are other animals such as butterflies which have 4 or 5 different photoreceptor types and can see more colors than us
Application such as the sun emits most of its radiation in the visible range which our eyes recognize as the color of rainbow.
Spectroscopy basically involves the study of the interaction of radiated energy with matter. These different radiations could be used to study chemical and physical material properties of different atoms. Colors of light differ in wavelength and energies and when they interact with matter, the light is either scattered, reflected, transmitted, absorbed, reflected or fluorescence. The interaction makes vibrational, electronic or nuclear changes in energy levels. This difference between energy levels includes a range of electromagnetic spectrum. Types of electromagnetic radiation include gamma rays, x-rays, ultraviolet, visible, infrared, microwaves and radio wave. Energies, wavelengths, frequencies, or wave number can be used to describe the radiations.
In the world of fascinating sights, colors are all are found everywhere in all sorts of ways. Colors are put into categories and types depending on what one is looking at. Some categories of colors may include: value-tints/shades, complementary colors, analogous colors, cool colors, warm colors, and neutral colors. The types of colors within these categories include: primary, secondary, tertiary, complementary, analogous, active and passive colors. These types and categorizes can be seen in a circular diagram that is divided by hue, saturation, and value called, the color wheel. The color wheel consists of all colors that are within the visible spectrum. The electromagnetic spectrum A basic color wheel includes: red, orange, yellow, green, indigo, and violet. As one looks cl...
waves are further divided into two groups or bands such as very low frequency (
The Eye is the organ of sight. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he/she is really seeing is the light that the object reflects, or gives off.
