Quiz 2

Sunburns are caused by ultraviolet (UV) light, not visible light, even though, as the graph below shows, the visible part of sunlight is more intense than the ultraviolet part. Ultraviolet light has a shorter wavelength than visible light. Which conclusion is BEST supported by this information?

• Shorter wavelength electromagnetic radiation has higher speed.

• Shorter wavelength electromagnetic radiation has more energy.

• Shorter wavelength electromagnetic radiation has greater charge.

• Shorter wavelength electromagnetic radiation has greater mass.
