In a wave, an area where coils are spread out is called a...

rarefaction

Which letters are at rest position?

A, C, E, and G

Wave your arms in the air like you just don't care and get these points.

Did you do it?

Which letters are crests?

B and F

If I increase the amplitude by a factor of 3, by how much would the wave energy increase?

A factor of 9 (remember - it's amplitude squared!)

Which letter represents wavelength?

A

wave speed = wavelength x frequency... If the wavelength is 12 m and the frequency is 4 Hz, what is the wave speed?

48 m/s

What word describes the number of waves that pass a point during a certain amount of time?

frequency

If I know that a wave pulse occurs in 5 seconds, what can I use that to calculate: frequency, amplitude, wave speed, or wavelength?

wave speed

What is the difference between a longitudinal and a transverse wave?

Longitudinal waves move parallel to the direction they are traveling, transverse waves move perpendicular to the direction they are traveling.

How could I measure the amplitude of a wave?

From rest position to the trough or rest position to the crest

How could I measure the wavelength of a wave?

From any point in the wave to the next same point (i.e. crest to crest OR trough to trough)

How many wavelengths are shown in the picture?

2

TRUE or FALSE: If everything else is the same, a wave with a smaller amplitude has more energy.

False

Do "the wave" as a team and get these points!

Which letters are troughs?

D and H

wave speed = wavelength x frequency... If the wave speed is 42 m/s and the wavelength is 6 m, what is the frequency?

7 Hz

All waves must travel through a ________.

medium

wave speed = wavelength x frequency... If the wave speed is 9 m/s and the frequency is 3 Hz, what is the wavelength?

3 m

In a wave, an area where coils are pressed together are called a...

compression

Which letter represents amplitude?

B

What unit is used to describe frequency?
