Question

A sound wave has a frequency of $\nu$ Hz and a wavelength of $\lambda$ m. Its velocity is:

• A. $\lambda {\nu }^{-1}$
• B. $\nu {\lambda }^2$
• C. $\nu {\lambda }^{-1}$
• D. $\nu \lambda$

Answer 1

The correct option is D $\nu \lambda$

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: $\nu \lambda$
