Question

How far does the sound travel in air when a tuning fork of frequency 256 Hz makes 64 vibrations? (Velocity of sound in air = 320 m/s)

Answer 1

Answer:

Speed = Distance/Time

Then,

Distance=Speed×Time

Therefore,

Distance=320 X 64/256

=80m Ans

Answer 2

The distance traveled by the sound wave is 80 meters.

Explanation:

Given that,

Frequency of the tuning fork, f = 256 Hz

Number of vibrations, n = 64

We need to find the distance traveled by the sound in air. We know that the number of vibration per unit time is given by :

$f=\dfrac{n}{t}$

$t=\dfrac{n}{f}$

$t=\dfrac{64}{256}$

t = 0.25 seconds

The velocity of sound is given by total distance divided by total time taken. It is given by :

$v=\dfrac{d}{t}$

$d=vt$

$d=320\times 0.25$

d = 80 meters

So, the distance traveled by the sound wave is 80 meters. Hence, this is the required solution.
