Sunscreen bottles often include the phrase: “Protects against UVA and UVB waves.” This refers to ultraviolet radiation coming from the sun. Which of the following is true of ultraviolet radiation?

• Ultraviolet radiation has shorter wavelengths than x-rays, therefore it is more dangerous than xrays.

• Ultraviolet radiation has longer wavelengths than infrared light, therefore it is more dangerous than infrared light.

• Ultraviolet radiation has shorter wavelengths than visible light, therefore it is more dangerous than visible light.

• Ultraviolet radiation has longer wavelengths than gamma radiation, therefore it is more dangerous than gamma radiation.

A rainbow is sunlight disbursed into a spectrum of colors ranging from red to violet. When you are facing a rainbow, the sun is always behind you, the rain is in the direction of the rainbow, and the arc of the rainbow is directly opposite the sun. Which statement best describes the formation of a rainbow?

• Tiny water droplets absorb the light waves that strike them disbursing the light into colored arcs.

• Light travels faster after the rain due to increased moisture in the air.

• Light in absorbed by the tiny water droplets in the atmosphere.

• The water droplets in the air refract the light waves separating the light into colored arcs.
