Q. Two tuning forks have frequencies $450\ Hz$ and $454\ Hz$ respectively. On sounding these forks together, the time interval between successive maximum intensities will be
A) $1/4\ sec$
B) $1/2\ sec$
C) $1\ sec$
D) $2\ sec$
Explanation
(a) The time interval between successive maximum intensities will be
$\frac{1}{n_{1}\sim n_{2}} = \frac{1}{454 - 450} = \frac{1}{4}\sec$
