Theory:
The purpose of this experiment was to demonstrate and better understand thin lenses. The two types of thin lenses are concave where the lens curves in and convex when the lens curves out. There are three characteristics of thin lenses, which include; a chef ray, which goes through the center of the lens and does not deviate, the parallel ray that shines parallel to the lens and is refracted through the focal point on the opposite side, lastly there is the focal ray, which shines through the focal point that is on the same side of the lens as the object and at the middle of the lens is refracted parallel to the lens. At the point where two or more reflections of the rays meet is where the image is created. A real image is one that is created on the opposite side on the lens compared to the object and a virtual image is one that is created on the same side of the lens as the object. An upright image is one that is right side up and has a positive magnetic factor, and an inverted image is one that is flipped up side down and has a magnetic factor that is negative. If an image i...

Applications of Physics For Different Industries Essay example

- INTRODUCTION Physics attempts to describe the fundamental nature of the universe and how it works, always striving for the simplest explanations common to the most diverse behaviour. For example, physics explains why rainbows have colours, what keeps a satellite in orbit, and what atoms and nuclei are made of. The goal of physics is to explain as many things as possible using as few laws as possible, revealing nature's underlying simplicity and beauty. Physics has been applied in many industrial fields, which include the air industry, construction industry, automobile industry, manufacturing industry and many others....   [tags: Physics]
