Equation of a progressive wave is given by $y = a\sin{\pi\left\lbrack \frac{t}{2} - \frac{x}{4} \right\rbrack,}$ where $t$ is in seconds and $x$ is in meters. The distance through which the wave moves in $8\ sec$ is (in meter)

Question

Dr. Abubacker · Accepted Answer

(b) $v = \frac{Co - efficient\ of\ t}{Co - efficient\ of\ x} = \frac{1/2}{1/4} = 2m/s$
Hence $d = vt = 2 	imes 8 = 16m$
