Question

A wave 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

Answer 1

a. 13 hz

Step-by-step explanation:

v (velocity)= 5.2 m/s

upside down y (wavelength)= 0.40 m

f (frequency)= unknown

------------------------

f= v/upside down y

f= 5.2/0.40

f= 13 hz

------------------------

this came straight from [a p e x].. hope this helps!!

Answer 2

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
