Behavior of Light

Behavior of Light

Light: What is it?

A form of energy we can see

Multiple Choice

Light is energy we can touch.

• True

• False

Because of Light - Objects can be seen when they

• Give off light

• reflect light (bounce light off the surface)

Multiple Select

What are the two ways objects can be seen?

• It gives off light

• It smokes.

• It reflects light.

• It rusts.

Light Travels: Straight Line

• Light travels this way until it hits something

Multiple Choice

Light always travels in a strait line, even when it hits something.

• True

• False

Light Travels: Reflection

• Light bounced off an object with a smooth surface.

• Light will reflect at the same angle that it hit the reflective object.

• Rough surfaces scatter light instead of reflecting it.

Multiple Choice

Light reflects off a smooth surface the same way it reflects off a rough surface.

• True

• False

Light Travels: Absorption

• Light is absorbed (taken in) by an object.

• The object gets warmer as the light changes to heat (thermal) energy.

Multiple Choice

When light gets taken in by an object, it is

• absorption

• reflection

• refraction

• transmission

Multiple Choice

The more light an object absorbs, the more heat energy it will make.

• True

• False

Light Travels: Refraction

• Light transmits through an object.

• It changes direction when it passes from one material (medium) to another.

• It is the bending of light.

Multiple Choice

When light goes from one medium (material) to another, it will bend. This is called

• absorption

• reflection

• refraction

• transmission

Seeing Color

• Different materials absorb more light of certain colors and reflect more light of other colors.

• Colors are the way we see reflected light.

Multiple Choice

The colors we see are the light that gets reflected off of the object.

• True

• False

To See Color: Black

• The object absorbs most colors of light

• Light energy changes to heat energy

Multiple Choice

What color is only seen when most of the colors of light are absorbed by an object?

• black

• green

• orange

• white

To See Color: White

• The object reflects most colors of light

• Not as much chance for light energy to change to heat energy.

Multiple Choice

What color is only seen when most the colors of light are reflected off the object?

• black

• green

• orange

• white
