A tuning fork vibrates with a frequency of $256 Hz$ . Taking the speed of sound to be $345.6 m s^{- 1}$ in the air, find the wavelength and the distance, which the sound travels during the time, fork makes $60$ vibrations.

Options:

Answer:

Solution:

Here, $f = 256 Hz; υ = 345 .6 m s^{- 1}$

$∴ λ = \frac{υ}{f} = \frac{345.6}{256} = 1 .35 m$

In one cycle, sound advances by distance $λ$

Therefore, the required distance travelled by sound,

$S = 60. λ = 81 m$
