If the freque...

Question

If the frequency of a transverse wave is $10 H z$ . And the distance between the two consecutive wave crests is $2 m$ . Calculate the wave speed.

Open in App

Solution

Frequency $f = 10 H z$
Distance between the two consecutive wave crests is equal to wavelength of wave
$∴ λ = 2 m$
as we know
$v = w a v e s p e e d = f λ = 10 \times 2 = 20 m / s e c$
