When a material allows the passage of light,

• the material reflects the light and changes

• the material absorbs the light and does not change

• the material transmits the light and does not change

• the material transmits the light and changes

How can we perceive an object as white in color?

• All colors of visible light are absorbed by an object and then reflected into our eye.

• All colors of visible light are reflected by an object and then into our eye.

• All colors of visible light are absorbed by an object and no light is reflected into our eye.

Maya wonders what types of light could heat an aluminum sheet. The table below shows what happens when different types of light hit the aluminum.

• X-ray light is more likely to heat the aluminum because X-ray light can extract energy from the aluminum when it passes through the aluminum.

• Ultraviolet light is more likely to heat the aluminum because ultraviolet light bounces off the aluminum, which means 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.

• No type of light is likely to heat the aluminum because the aluminum does not absorb energy from either X-ray light or ultraviolet light.

A material absorbs energy from some types of light and not others. Is this statement true or false?

• True, for example, a green plant absorbs red and blue light while reflecting green light.

• True, as long as the temperature of the light is the same.

• False, an object either absorbs light or it doesn't, it can't do both.

• False, since light is neither created nor destroyed, all objects must absorb light.

Why does a black object heat up when exposed to light?

• because it reflects all types of visible light that reach it

• because it absorbs all types of visible light that reach it

• because all types of light carry energy

• because light is warm

Can the sun damage the paint on your house since it is exposed to sunlight every day?

• Yes, the paint can absorb energy from the light, causing damage.

• No, light can only damage things by heating them, so it cannot damage the paint on the house.

• No, light is not a physical thing, so it cannot change physical things like the paint on the house.

• Yes, light can extract energy from the paint, causing damage.
