Frequency of 2 hertz and wavelength of 5 meters. Calculate speed.

Speed = 10 m

Explanation:

Given

wavelength = 5 m

frequency = 2 Hz = 2

Speed = ?

We know that for all waves, the relationship between wavelength λ, frequency f and speed v is same and given by the equation:

                                v = fλ

Hence, Speed = 2 x 5 m

                         = 10 m

option number c is the right answer.
