Awave travels through a medium at 251 m/s and has a wavelength of 5.10 cm. what is its frequency? what is its angular frequency? what is its period of oscillation?

Explanation:

It is given that,

Speed of a wave, v = 251 m/s

Wavelength of the wave, λ = 5.1 cm = 0.051 m

(1) The frequency of the wave is given by :

(2) Angular frequency of the wave is given by :

(3) The period of oscillation is given by T as :

T = 0.000203 seconds

or

T = 0.203 milliseconds

Hence, this is the required solution.

the answer is a)
