The frequency of a tuning fork is 220 ~Hz and the velocity of sound in air is 330 ~m / s . When the tuning fork completes 80 vibrations, the distance travelled is

Options

  1. A120 ~m
  2. B60 ~m
  3. C53 ~m
  4. D100 ~m

Correct answer

A. 120 ~m

Step-by-step solution

aligned & f =220 ~Hz , v=330 ~m / s & v= f & = v f = 330 220 = 3 2 ~m aligned Distance travel in 80 vibrations =80 3 2 =120 ~m
