Speed of the sound wave is given by, v =_____.

The correct option is B f × λ Speed of sound in terms of frequency and wavelength of the wave is given by, v = f × λ i.e. Speed of sound is the product of frequency and wavelength of the wave.

The correct option is B
f $\times$ λ

Speed of sound in terms of frequency and wavelength of the wave is given by,

v = f $\times$ λ

i.e. Speed of sound is the product of frequency and wavelength of the wave.
