Question

A tuning fork has a frequency of $256Hz.$ Distance traveled by sound emitted during the time it makes $16$ vibrations is $(v=332m/s)$

• A. $256m$
• B. $332m$
• C. $20.7m$
• D. $256\times 16m$

Answer 1

Answer: (C)

$20.7m$

Given, the frequency of a tuning fork $256Hz$.

We have to find the distance it travels during the time it makes 16 vibrations.

The tuning fork makes $256$ vibrations in $1s$.

So, for $16$ vibrations, it takes $\frac{1}{256}\times 16=\frac{1}{16}s$

During this time, the distance travelled is $v\times t=332\times \frac{1}{16}\approx 20.7m$

So, C is the correct answer.
