Hector looks around his classroom at different objects. Which object reflects almost all of the light that strikes it?

Question 1 options:

white poster board

clear window glass

bright overhead light

black construction paper

Hey there!

Your answer is a. white poster board.

The color an object appears as depends on what colors of light are reflected vs absorbed.

If an object appears as black, that means it doesn't reflect light, but it absorbs the light.

If an object appears as white, that means it doesn't absorb light, but it reflects the light.

White light is all colors of light mixed together.

So, the white poster board is the object reflecting almost all the light that strikes it.

Hope this helps!

White poster board  

Explanation:

White light consists of all the colours in the rainbow. A white poster board reflects almost of the white light that hits it, so it appears white to our eyes.

B is wrong. Clear window gas is transparent. Almost all the light that hits it passes straight through

C. is wrong. A bright overhead light is a light source. It is generating its own light.

D is wrong. Black construction paper absorbs almost all the light that hits it. It reflects no light to our eyes, so it appears black.
