MCQ
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 .... $sec$
  • $0.25$
  • B
    $0.5$
  • C
    $1$
  • D
    $2$

Answer

Correct option: A.
$0.25$
a
(a) The time interval between successive maximum intensities will be

$\frac{1}{{{n_1}\sim{n_2}}} = \frac{1}{{454 - 450}} = \frac{1}{4}\sec .$
