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.

Which type of light wave produces the heat we can feel coming from the toaster?

• Radio waves

• Infrared waves

• X-rays

• Gamma rays

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.

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.
