Question

What is the speed of a 10 Hz wave with a wavelength of 5 m?

Answer 1

Answer:

Speed of wave = 50m$s^{-1}$

Explanation:

Given

Wavelength of wave = 5 m

Frequency of wave = 10 Hz = 10$s^{-1}$

speed of wave = ?

We know that all waves have same relationship among wavelength λ, frequency f and speed v, which is given by

           v = fλ

Therefore speed of wave = 10$s^{-1}$ x 5 m

                                           = 50 m$s^{-1}$
