What happens when light passes through air?

• It is transmitted in a curved line.

• It is transmitted in a bent line.

• It is transmitted in a straight line.

• It is transmitted in a spiral line.

What happens when light passes from air into water?

• It is transmitted in a straight line until it hits the water; then the light bends at an angle.

• It is transmitted in a straight line until it hits the water; then the light curves into the water.

• It is transmitted in a straight line until it hits the water; then the light spirals down into the water.

• It is transmitted in a straight line through the air into the water.

What happens when light passes from air into glass?

• It is transmitted in a straight line through the air into the glass.

• It is transmitted in a straight line until it hits the glass; then the light spirals down into the water.

• It is transmitted in a straight line until it hits the glass; then the light curves.

• It is transmitted in a straight line until it hits the glass; then the light bends at an angle.

What else happens to light when it hits water or glass besides transmission?

• Some of the light is refracted back into the air.

• Some of the light is reflected back into the air.

• Some of the light is diffused back into the air.

• None of the choices given.

We only see the colors that are____ off a surface.

• reflected

• refracted

• diffused

• absorbed

How can white light be separated into its various colors?

• Through refraction.

• Through diffraction.

• Both of the choices given.

• Neither of the choices given.
