Wave Properties
How waves travel
100

This is the highest point on a wave.

What is a crest?

100

This is when a wave crosses a boundary between two different kinds of materials.

What is refraction?

200

This is the distance from one crest to the next crest or one trough to the next trough.

What is wavelength?

200

This is when a wave passes through a small opening.

What is diffraction?

300

These are the two main types of mechanical waves discussed.

What are transverse and longitudinal waves?

300

Sound waves travel at this speed.

What is 343 m/s?

400

This is the maximum amount of displacement from the resting point of the wave.

What is the amplitude?

400

All electromagnetic waves travel at this speed.

What is 300,000,000 m/s?

500

This is how a longitudinal wave travels.

What is perpendicular to the direction of oscillations?
