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

540m/s

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
