Chapter 1 Lesson 3 Review

Master light properties like refraction, reflection, and absorption!

Match each word to its definition. Refraction the bending of light when it passes into a new medium Reflection occurs when light rays bounce off a surface Absorption occurs when an object takes in light waves Prism a piece of glass that separates white light into its different wavelengths What is bioluminescence light the result of? a firefly rubbing its wings together a light reaction a chemical reaction inside the animal's body Type the word(s) that correctly completes the sentence. Double check your spelling. The form of light energy that we can see is call visible light. Type the word(s) that correctly completes the sentence. Double check your spelling. Light energy travels from its source as waves. Type the word(s) that correctly completes the sentence. Double check your spelling. The colors of the visible light spectrum are arranged by their wavelengths and frequencies. What colors make up the visible light spectrum? Use at least one complete sentence to answer the question. Does the color red have a lower frequency or a higher frequency that the color green? Higher frequency Lower frequency It has the same frequency What causes the light to refract when passing through a new medium? The change in speed. The light bounces off the the new medium. The colors bend to go around the new medium. Light doesn't refract. Type the word(s) that correctly completes the sentence. Double check your spelling. Objects with smooth, shiny surfaces reflect more light rays than other objects. What happens to an object that absorbs a lot of light? It turns black. It gets cold. It gets hot. It turns white.
