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:

Answer:

Solution:

$f = 220 Hz, v = 330 m / s v = f λ λ = \frac{v}{f} = \frac{330}{220} = \frac{3}{2} m$ Distance travel in 80 vibrations $= 80 \times \frac{3}{2} = 120 m$
