Q. Two tuning forks A and B produce 4 beats/sec. Forks B and C produce 5 beats/sec. Forks A and C may produce ……. beats/sec

In This post you will get answer of Q.
Two tuning forks A and B produce 4 beats/sec. Forks B and C produce 5 beats/sec. Forks A and C may produce ……. beats/sec

Solution:

We consider two possible cases about tuning forks $A, B$ and $C $

Case I When $A$ and $B$ are tuned, four beats are produced. When $B$ and $C$ are tuned, five beats are produced.

So, there is a difference of 1

$left|n_{A}-n_{C}right|=1$

Case II When $A$ and $C$ are tuned, the total number of beat produced.

$left|n_{C}-n_{A}right|=4+5=9$
