Physics - Wave on String Question with Solution | TestHub

Sound wave equation is,

$y=0.0015 \sin (62.4x + 316t)$

Standard equation of wave motion is,

$\text{y}=\text{A sin }2\pi \left[\frac{\text{x}}{\lambda }+\frac{\text{t}}{\text{T}}\right]$

Comparing the given equation with the standard equation, we get

$\frac{2\pi }{\lambda }=62.4$

or, the wavelength of the wave,$\lambda =\frac{2\pi }{62.4}=0.1 \mathrm{unit}$
