Review - Wave Properties

The illustration shows a light ray striking an object.
In the illustration, the light ray striking the object is-

• absorbed
• stopped
• reflected
• refracted

A student placed a pencil in a cup of water.  The pencil appears broken because light-

• always travels in a straight line
• bends when it passes through water
• makes the water in the glass evaporate
• reflects the pencil on the water's surface

The bouncing off of light rays from the surface of an object such as a mirror or other shiny surface is called:

• mirror
• laser
• reflection
• refraction

Light bending as it passes through a rain drop is an example of...

• Refraction
• Reflection

Refraction is the bending of a wave disturbance as it passes from one _________ into another.

• glass
• medium
• area
• boundary

Why do we see grass as green?

• Green light is absorbed

• Green light is reflected

What would you call this?

• Bounce back

• Reflection

• Diffraction

• Refraction

Refraction occurs when _____________

• the wave's speed changes by entering a new medium
• a wave bounces off of a boundary
• waves parts meet each other
• waves bend around a barrier

Light waves bouncing off of this lake is an example of:

• Reflection

• Refraction

• Absorption

The substance that a wave is passing through

• medium

• frequency

• wavelength
