Light Waves Study Guide (Amplify)

A rug sits in a sunny place on the floor for a long time. Kiara thinks that light from the sun can cause the rug’s color to fade over time. Can light from the sun cause the rug’s color to fade?

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

• No. Light can only change things by warming them up, so it cannot cause the rug’s color to fade.

• Yes. The rug can take in energy from the light, causing the rug’s color to fade.

• Yes. Light from the sun can pull energy out of the rug, causing the rug's color to fade.

Aniyah has a special type of paper that can permanently change color. She wonders whether light can cause the paper’s color to change. The table below shows what happens when different types of light hit the paper. Based on this information, which type of light can cause the paper to change color?

• The infrared light can cause the paper to change color.

• The X-ray light can cause the paper to change color.

• The ultraviolet light can cause the paper to change color.

• Any of these types of light can cause the paper to change color, because all light carries energy that can cause materials to change.

Ana wonders how light can affect a mystery material. The table below shows what happens when different types of light hit the mystery material. Based on this information, can light change the mystery material?

• Yes, but the mystery material can change in only one way, such as by getting warm, because all the light that a material absorbs will affect that material in the same way.

• Yes, and the mystery material can change in one or two different ways, such as by getting warm and/or changing color, because different types of light can cause different changes to a material when they are absorbed.

• No. The mystery material can’t change because light is not a physical thing. Light cannot change physical things like the mystery material.

• There is no way to know whether the mystery material will change or not.

Wei saw a special type of plastic that would melt and become a liquid when it was placed in the sun, but it would not melt when placed under a desk lamp. Why does light from the sun melt the plastic when light from the desk lamp does not?

• Because the plastic can take in energy from the light from the sun, but not from the light from the lamp.

• Because light from the sun carries heat molecules, and light from the desk lamp does not.

• Because light from the sun pulls energy out of the plastic, and light from the desk lamp does not.

• Because the sun gives off a type of light that carries energy, and light from the desk lamp does not.
