Question 444: Waves

Question

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

Accepted Answer

Period $$=\mathrm{\frac{1}{n}}$$
Time required for x vibrations, $$\mathrm{t=\frac{x}{n}}$$
Distance travelled by the wave, $$\mathrm{Vt=\frac{xV}{n}}$$

Answer

$$\mathrm{\frac{V}{xn}}$$

Answer

$$\mathrm{\frac{Vn}{x}}$$

Answer

$$\mathrm{\frac{xV}{n}}$$

Answer

$$\mathrm{\frac{x}{Vn}}$$
