Light

Light travels continuously until it hits an object. In what path does light travel?

• straight line

• spiral line

• bent line

• curved line

In this picture, the pencil appears broken. As light waves move from one material into another, they bend and change direction. This is called...

• refraction

• spreading

• reflection

• scattering

By passing white light through a prism, you can tell —

• that white light is actually a mixture of different colors 

• the original source of the light

• the mass of the prism

• that blue light is brighter than white light

The electromagnetic spectrum is made up of

• Red, Orange, Yellow, Green, Blue, Indigo, Violet

• Red, Blue, Yellow

• Red, Green, Blue, Purple

How is a rainbow formed?

• When it rains, the air reflects all of the colors in a rainbow

• We only see rainbows when it is raining

• Some light is absorbed by air and some is reflected by the raindrops

• Light rays pass through raindrops and refract

Explain why this pencil looks "broken"

• Light is reflecting off of the glass.

• The water is hot and snaps the pencil in half.

• The light is absorbed by the water.

• The light waves are refracted because they slow down when they hit the water.

When light hits an object, it is sometimes absorbed by that  object. What is the process that describes when light bounces off an object?

• refraction

• reflection

• rotation

• diffraction
