Question

When two sound sources are sounded together then 2 beats are produced in 20 seconds find the frequency of the beats

Answer 1

frequency = beats\second

= 20\2

=10

Answer 2

Answer: The frequency of the beats is $f = \dfrac{1}{10}\ Hz$.

Explanation:

Given that,

Number of beats = 2

Time taken t = 20 sec

We know that,

The beat frequency is the  number of beat per second.

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

$f = \dfrac{2}{20}$

$f = \dfrac{1}{10}\ Hz$

Hence, The frequency of the beats is $f = \dfrac{1}{10}\ Hz$.
