Question

A 18000 Hz wave has wavelength of 0.03 meters. How fast is this wave
traveling?

Answer 1

540m/s

Step-by-step explanation:

Given parameters:

Frequency of the wave = 18000Hz

Wavelength of the wave = 0.03m

Unknown:

How fast is the wave traveling = ?

Solution:

How fast the wave is traveling is a measure of the speed of the wave;

Speed of wave = frequency x wavelength

Now insert the given parameters and solve;

Speed of wave = 18000 x 0.03 = 540m/s
