• surface...incident

• surface...reflected

• normal...incident

• normal...reflected

The angle of refraction is measured between the ______ and the _________ ray

• surface...incident

• surface...refracted

• normal...incident

What show the direction of waves?

• Rays

• Wavefronts

What is a line that connects all the peaks?

• Rays

• Wavefronts

What is the angle between rays and wavefronts?

• 0 degrees

• 45 degrees

• 90 degrees

• 180 degrees

When a wave goes into a slower medium the wavefronts:

• Stay the same distance apart

• Get further apart

• Get closer together

When a wave goes into a faster medium the wavefronts:

• Stay the same distance apart

• Get further apart

• Get closer together

The distance between wavefronts is the

• Amplitude

• wavelength

• frequency

• Time period
