How many wavelengths are shown in the picture?

2

Which letter represents wavelength?

A

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

Did you do it?

Which letters are at rest position?

A, C, E, and G

Which letter represents amplitude?

B

What unit is used to describe frequency?

Hertz (Hz)

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

False

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.

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

Did you do it?

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

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

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 pressed together are called a...

compression

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!)

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)

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

rarefaction

All waves must travel through a ________.

medium

How could I measure the amplitude of a wave?

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

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

Did you do it?

Which letters are troughs?

D and H

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

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
