12 Bonus -3pts eachName three electromagnetic waves and tell me one way it is used in our lives.Give me three different media that light can travel through. Air, water, glassExplain how you see a red apple as the color red. Red light is reflected off the apple to our eyes, the other colors are absorbed.When white light is refracted by a prism, what happens to the light you see? Why? White light is refracted and separated into the rainbow colors because white light is made up of these colors. The different wavelengths are seen as colors
