Awave travels at a speed of 5.2 m/s. if the distance between crests is 0.40 m, what is the frequency of the wave? use f=v/wavelength a. 13 hz b. 2.1 hz c. 0.077 hz d. 5.6 hz

A. 13 Hz.

The way to solve this problem is using the equation f = v/λ, where f is the frecuency of the wave, v the velocity of the wave and λ is the wavelength.

A wave travels at a speed of 5.2 m/s and the distane between crests is λ = 0.40 m. To find the frecuency of the way:

f = v/λ = 5.2 m/s / 0.40 m

f = 13 s⁻¹

f = 13 Hz
