Question
The frequency of sound wave is $\mathrm{n}$ and its velocity is $\mathrm{v}$ if the frequency is increased to $4 n$ the velocity of the wave will be(a) $v$(b) $2 v$(c) $4 v$(d) $v / 4$
Step 1
Step 1: The velocity of a wave is given by the formula $v = f \lambda$, where $v$ is the velocity, $f$ is the frequency, and $\lambda$ is the wavelength. Show more…
