Why does this car appears red under a white light?

• The car is absorbing the red light and reflecting the blue and green.

• The car is reflecting only the red light while absorbing the blue and green.

• The car is absorbing the red and green light while reflecting the blue.

• The car is absorbing the red, blue and green, but our eyes can only see the red.

If a car sits out in the sun every day for a long time, can light from the sun damage the car’s paint?

• Yes. The paint can take in energy from the light, causing it to be damaged.

• No. Light can only change things by warming them up, so it cannot damage the car’s paint.

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

• Yes. Light from the sun can pull energy out of the paint, causing it to be damaged.

Shonda is learning about a new kind of material that might be used to make new satellites, and she wonders if light can damage the material. Results show that X-ray light reflects off the material while gamma ray light transmits through the material. Based on this information, which type of light is more likely to damage the material?

• The gamma ray light is more likely to damage the material because the gamma ray light can pull energy out of the material when it passes through the material.

• The X-ray light is more likely to damage the material because the X-ray light bounces off of the material, which means that it has more energy.

• There is no way to know because they are two different types of light, and different types of light can change a material in different ways.

• Neither type of light is likely to damage the material because the material does not take in energy from either the X-ray light or the gamma ray light.

Kayla wonders if lasers will be able to cut a hole in a piece of silicone. Results show that helium-neon laser light reflects off the silicone, carbon dioxide laser light is absorbed by the silicone, and diode laser light is transmitted through the silicone. Based on this information, which type of laser light can cut a hole in the silicone?

• The helium-neon laser can cut a hole in the silicone.

• The carbon dioxide laser can cut a hole in the silicone.

• The diode laser can cut a hole in the silicone.

• Any of these types of light can cut a hole in the silicone, because all light carries energy that can cause materials to change.
