A wave with a speed of 437 m/s has a frequency of 28 hertz. What is the length of the wave?

Answer: 15.6 metres

Explanation:

Given that:

length of wave (λ) = ?

Frequency of wave F = 28 Hertz

Speed of wave (V) = 437 m/s

The wavelength is the distance covered by the wave in one complete cycle. It is measured in metres, and represented by the symbol λ.

So, apply V = F λ

Make λ the subject formula

λ = V / F

λ = 437 m/s / 28 Hertz

λ = 15.6 m

Thus, the length of the wave is 15.6 metres
