Light and Optical Systems Quiz Name: _________________ 1. Describe 3 of the 8 properties of light. . _ 1 ____________________________________ 2. _____________________________________ 3. _____________________________________ 2. Describe a specific (real-life) example of one of the following: - Refraction: _____________________________________________________________ _____________________________________________________________ - Reflection: _____________________________________________________________ _____________________________________________________________ - Absorption: ____________________________________________________________ ____________________________________________________________ . What is the difference between something that is luminous and something that is 3 non-luminous? Give an example for each ____________________________________________________________________________ ____________________________________________________________________________ 4. Use the “Ray Model of Light” to help you answer the following questions a) Use a ruler and pencil to complete the ray diagram below to show how the object in front of the candle creates a shadow on the wall behind it. b) What would happen to the object’s shadow if you moved the object closer to the candle? ___________________________________________________________________________ _ 5. Use the following words to complete the sentences below. Words may be used once, more than once or not at all. translucent opaque reflected absorbed When light rays hit a _____________________ surface such as cardboard or a mirror, it can be __________________ or _______________________. 6. Describe the law of reflection using the words below: concave convex diverge converge ____________ mirrors reflect light rays so that they ______________, meaning they spread out. While _____________ mirrors ____________ light rays to a single focus point. 7. Answer the following questions. a) Use a ruler and pencil to complete the ray diagrams below. b) Label each mirror as concave or convex. . Label the diagram below using the following five terms: reflected ray (R) angle of reflection (r) 8 incident ray (I), angle of incidence (i) and the normal line (n). 9. Look at the ray diagram below then answer the following questions. . Is the light ray speeding up or slowing down in the diagram above? How do you know? a ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ b. The angle of incidence is _________________ (greater/less) than the angle of refraction. 0. Use a ruler and pencil to help you complete the ray diagrams below. Show what happens to 1 parallel light rays passing through each lens below. 1. Describe the image in the convex lens when you look at an image that is close to you. Does 1 it change as the object moved farther away? If so, how does it change? ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ 2. When white light is broken into colours what are the colours and in which order do they 1 appear.
