Question

another property of longitudinal waves is frequency. just as in transverse waves, frequency is the number of wave cycles that pass a fixed point in a certain amount of time. frequency is usually measured in hertz (hz), with 1 hertz being equivalent to 1 wave cycle per second.

for example, if eli creates a wave in a spring toy so that 2 compressions pass a point every second, the frequency is 2 hertz.
if eli creates a wave so that 6 compressions pass a point every 2 seconds, what is the frequency of the wave?
□ hz

Explanation:

Step1: Define frequency formula

Frequency $f = \frac{\text{Number of cycles}}{\text{Time}}$

Step2: Substitute given values

$f = \frac{6}{2}$

Step3: Calculate the result

$f = 3$

Answer:

3 Hz
