Amplify Light Waves Review

When a material allows light to pass through it,

• the material reflects the light and changes

• the material absorbs the light and doesn't change

• the material transmits the light and doesn't change

• material transmits the light and changes

• transmit

• increase

• absorb

How are we able to perceive an object as being the color white?

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

• All colors of visible light are reflected off an object and then to our eye.

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

Different types of light can affect the same material or object in different ways.

• True, for example radio waves are transmitted through plant cells while visible light is absorbed.

• False, because all light is the same.

• False, if an object can absorb light then it will be able to absorb it regardless of what type of light it is.

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

• The X-ray light is more likely to heat up the aluminum because the X-ray light can pull energy out of the aluminum when it passes through the aluminum.

• The ultraviolet light is more likely to heat up the aluminum because the ultraviolet light bounces off the aluminum, 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 heat up the aluminum because the aluminum does not take in energy from either the X-ray light or the 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 it reflects green light.

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

• False, an object will either absorb light or not, it can't do both.

• False, since light is not created or destroyed all objects must absorb light.

When light shines on a black object, why does it get warm?

• because it reflects all types of visibile 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
