Question

The equation of a progressive wave can be given by y=15 sin (660 $pi t$ -0.02 $pi x$ ) cm. the frequency of the wave is

330 Hz
342 Hz
365 Hz
660 Hz

The correct answer is: 330 Hz

Given that y=15sin (660 πt—0.02πx)
Comparing with general equation of progressive wave, we get
$y equals open parentheses x comma t close parentheses equals a sin invisible function application open parentheses fraction numerator 2 pi over denominator T end fraction t minus fraction numerator 2 pi over denominator lambda end fraction x close parentheses$
$therefore fraction numerator 2 pi over denominator T end fraction equals 660 pi$
$o r fraction numerator 1 over denominator T end fraction equals 330 blank o r v equals 330 blank H z$
