# The wavelength of a sound wave was measured

The wavelength of a sound wave was measured by Rohit as 8 m. The frequency of sound wave is given as 40. Hz. What is the speed of sound as calculated by Rohit?

Given, A = 8m and V = 40 Hz As speed of sound, v = v$\lambda$
.’. v = 40 x 8 = 320 m ${{s}^{-1}}$
