Question

A wave travels at 48 m/s and has a frequency of 12 Hz. What is the wavelength of the wave?

0.25 m
4.0 m
36 m
60 m

Answer 1

Wavelength = 4 m

Step-by-step explanation:

We know that Velocity = Wavelength × Frequency

So, Wavelength = Velocity / Frequency

Here in the question , Velocity = 48 m/s & Frequency = 12 Hz.

So wavelength = 48/12 = 4 m
