Equation of a progressive wave is given by $y = a \sin \pi \left[\frac{t}{2} - \frac{x}{4}\right],$ where t is in seconds and x is in meters. The distance through which the wave moves in 8 sec is (in meter)
Text Solution
Verified by ExpertsThe correct answer is:
B
$v = \frac{\text{Co-efficent of t}}{\text{Co-efficent of x}} = \frac{1/2}{1/4} = 2 \mathrm{m/s}$
Hence $d = vt = 2 \times 8 = 16 m$
