Answer 1

Answer: 60Hz

Step-by-step explanation:

Given that

Speed of wave V= 54m/s

Wavelength ( λ) = 0.90 m

Frequency of wave F = ?

Recall that the frequency of a wave is the number of cycles the wave complete in one secon, and it is measured in hertz.

So, apply the formula

V = F λ

F = V/ λ

F = 54m/s / 0.90 m

F = 60Hz

Thus, the frequency of this wave is 60 Hertz
