Transmitted light is...

• light that goes through an object.

• light that bounces off an object.

• light that heats up an object.

• light that comes from an object.

Reflected light is...

• light that goes through an object.

• light that bounces off an object.

• light that heats up an object.

• light that comes from an object.

Absorbed light is...

• light that goes through an object.

• light that bounces off an object.

• light that heats up an object.

• light that comes from an object.

How much light reached the colored water compared to the amount of light that reached the clear water?

• The same amount of light reached both beakers of water.

• Less light reached the colored water.

• More light reached the colored water

• The amount of light can not be measured.

Our investigation showed us that the more light that was reflected and or transmitted by the water...

• the less the water heated up.

• the more the water heated up.

Which color of water reflect the least light?

• clear

• dark colored

• neither will reflect light

• they both will reflect the same amount of light

Which color of water reflected the most light?

• clear

• dark colored

• neither will reflect light

• they both will reflect the same amount of light
