Wave Basics & Properties of Sound

The frequency of a tuning fork is 'n' Hz and velocity of sound in air is 'V' m/s. When the tuning fork completes 'x' vibrations, the distance travelled by the wave is

Show answer and solution

Answer: (c)

One vibration moves the wave forward by one wavelength $\lambda = \frac{V}{n}$ .
After $x$ vibrations: distance $= x\lambda = \frac{xV}{n}$
So the answer is (c) $\frac{xV}{n}$ .
