Answer: frequency = 6.5 Hz

Step-by-step explanation:

Given that the

Speed V = 65 m/s

Wavelength (λ) = 10m

Wave speed is the product of frequency and wavelength. That is,

V = fλ

Substitute V and (λ) into the formula to get frequency f

65 = 10f

Make f the subject of formula

f = 65/10

f = 6.5 Hz

Therefore, the frequency of this wave is 6.5 Hz?
