Which statement best describes what waves are?

• wavy lines on graph paper
• disturbances that transfer energy
• light energy that changes particles of matter
• circles that move out from a central place 

What is a vacuum? 

• A space with only air in it
• A space with NO matter at all present

Reflection is to bouncing as refraction is to:

• bending.

• breaking.

• dissipating.

• halting.

When a light ray strikes a smooth, flat surface, what is the relationship between the angle of incidence and the angle of reflection?

• They are equal.

• The angle of incidence is twice that of the angle of reflection.

• The angle of reflection is twice that of the angle of incidence.

• They combine to add up to 180^o.
