Question

A wave of wavelength 0.3 m travels 900 m in 3.0 s. Calculate its frequency.

Answer 1

Answer: 1000 Hz

Step-by-step explanation:

You can calculate frequency by dividing velocity by wavelength

Frequency = velocity/wavelength

Find velocity first.

900 m/3 s = 300 m/s

Plug values in to find frequency.

F = (300 m/s)/0.3 m

F = 1000 Hz
