You can see the color of all kinds of waves along the electromagnetic spectrum. 3. Visible light makes up a part of the electromagnetic spectrum. 4.Infrared waves have higher frequencies than visible light. 5.Light is an electromagnetic wave. 6. A light-year is the distance that light travels in a year. 7. All materials have the same natural frequencies. 8.Pigments selectively absorb certain frequencies of light so you can use them to color objects. 9.Rainbows appear only after a rainstorm if the weather is hot. 10. A transparent object will reflect the light that it does not absorb. 11.Refracted light travels in a straight line. 12. A transparent object will transmit the light that is does not absorb. 13.
