Your friends say that they saw a special nail polish that changes color when it is out in the sun. Can light from the sun cause the nail polish to change color?

• No. Light is not a physical thing, so it cannot change physical things like nail polish.

• Yes. Light from the sun can pull energy out of the nail polish, causing it to change color.

• Yes. The nail polish can take in energy from the light, causing it to change color.

• No. Light can only change things by warming them up, so it cannot cause the nail polish to change color.

• Reflect

• Absorb

These graphs show the wavelength and amplitude of light coming from three lasers. Could any of these lasers be giving off a different type of light?

• Yes. Laser 2 could be giving off a different type of light because Laser 2 has a different wavelength than Lasers 1 and 3.

• Yes. Laser 3 could be giving off a different type of light because Laser 3 has a different amplitude than Lasers 1 and 2.

• No. All three lasers must be giving off the same type of light because all three are lasers.
