...Transmitted Change of medium that is not too drastic to allow some of the wave to continue on its motion To cause (a disturbance) to propagate through a medium Plasma frequencies Frequency above which transmission does take place Specular reflections We see an actual image From a mirror or other smooth surface Reflection occurs in one direction Diffuse Reflections The scattering of incident light by reflection from a rough surface we see a “bright” color Reflection from a rough surface How we see most things Reflection occurs in multiple directions Refracted The bending of a beam of transmitted light at the interface of two media To break the natural course of, as rays of light or heat, when passing from one transparent medium to another of different density Index of Refraction For any medium we can calculate its index of refraction. The index of refraction compares the speed of light in that medium to the speed of light in a vacuum (“c”). Internally reflected Light is moving from a slower medium to a faster medium Fiber Optics The science or technology of light transmission through very fine, flexible glass or plastic fibers Pg5 A. A camera with a larger lens will make a much more clearer picture. A larger image can also be shown more clear from farther away. B. The purpose of a camera today is to refocus the lens and change sizes to fit the object that is being photographed so it is clear and the correct size. Pg7 A. B would be larger because it is closer to the hole. B. A would be right side up. This is because the shadow image would project the same backwards not...
