20
Q

What is the frequency of a wave?

A

The number of waves that pass through a certain point in 1 second

21
Q

What unit of measurement is used for frequency?

A

Hertz (Hz)

22
Q

What is the wavelength of a wave?

A

The distance between the start and end of a wave (after going up and down once from the central position)

23
Q

What unit of measurement is used for wavelength?

A

Metres (m)

24
Q

What is the peak/crest of a wave?

A

The highest point a wave reaches above the central position

25
Q

What is the trough of a wave?

A

The lowest point a wave reaches below the central position

26
Q

What is the amplitude of a wave?

A

How high/low the wave goes from the central position

27
Q

What is it called when the frequency of a wave is low (the waves are far apart)?

A

28
Q

What is it called when the frequency of a wave is high (the waves are close together)?

A

Compression

29
Q

What is the equation for the number of waves (in a certain amount of time)?

A

of waves = Frequency x Time Taken

30
Q

What is the equation for velocity (speed)?

A

Velocity = Frequency x Wavelength

31
Q

What is the equation for distance?

A

Distance = Speed x Time

32
Q

33
Q

What is a longitudinal wave?

A

A wave where the disturbance is parallel to the direction of the wave

34
Q

What is a transverse wave?

A

A wave where the disturbance is 90 degrees to the direction of the wave
