Lesson 4

Which type of waves transfers energy?

Maximum displacement of a wave is the.....

What is the amplitude?

the distance from 1 point on a wave to the next exactly similar point (ex crest to crest) is.....

1 / T = ?

Phase difference is...

• very dangerous

• when waves vibrate out of step

• the displacement

• measured in Joules

X represents

• displacement

• size

• the place where pirates hide their treasure

• wave

λ is the...

• height

• wavelength

• displacement

• symbol for the half-life video game

longitudinal waves vibrate

• at right angles to the direction or travel

• up and down

• parallel to the direction of travel

• very quickly

1 oscillation is

• 90 degrees

• 180 degrees

• 360 degrees

• 540 degrees
