Question

A device at the bottom of the sea emits a sound wave of frequency 200 Hz. (i) The speed of sound in sea-water is 1500 m / s. Calculate the wavelength of the sound in sea-water. [2]​

Answer 1

Answer:

7.5 Meters

Explanation:

You have been asked to find the wavelength given your speed to be 1500 m/s and a frequency of 200 Hz. The formula is "λ = v/f" where v = speed, f = frequency and λ = wavelength.

Therefore:  λ = v/f

                      = 1500/200

                      = 7.5 meters

Note: The S.I unit for wavelength is meters (m).
