Which letters are at rest position?

A, C, E, and G

What unit is used to describe frequency?

Hertz (Hz)

How could I measure the amplitude of a wave?

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

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

False

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

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)

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!)

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

Which letters are troughs?

D and H

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

compression

How many wavelengths are shown in the picture?

2

Do "wavy arms" for 15 seconds and get these points!

Did you do it?

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

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

Did you do it?

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

Did you do it?

Which letter represents amplitude?

B

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

Which letters are crests?

B and F

Which letter represents wavelength?

A

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.

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

frequency

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

rarefaction
