Question

What is the wavelength of a wave that has a speed of 350 meters/second and a frequency of 140 hertz?In meters

Answer 1

Answer: The wavelength is 2.5 meters.

Explanation: The wavelenght of a wave is related to the velocity and the frequency by the next equation:

Wavelenght = Speed/Frequency

so here we have:

W = (350 m/s)/(140Hz)

Now we may do the change of unit Hz = 1/s and get:

W = (350m/s)/(140 1/s) = (350/140)m = 2.5m

Answer 2

Apply:
wavelength = speed/frequency
= 350 m/s : 140 Hz = 2.5 m.
