Question

A sound wave has a frequency of ν Hz and a wavelength of λ m. Its velocity is.

• A. $\frac{\nu }{\lambda }$
• B. $\nu \lambda$
• C. $\nu {\lambda }^2$

Answer 1

The correct option is B $\nu \lambda$

The velocity with which the wave travels through the medium is called wave velocity. In other words, the distance travelled by a sound wave in unit time is called the velocity of a sound wave.
It is given by the product of the wavelength and frequency of the wave: $\nu \lambda$
