The displacement of a wave travelling in the x direction is y=10^-4 sin ⁡(600t-2x+ 3)m, where x is in metre and t in second. The speed of the wave is

Question

Accepted Answer

Correct answer: A. (a) The given equation, y=10^-4 sin ⁡(600t-2x+ 3)m On comparing this equation with standard equation with y= Asin ⁡ ( ωt- kx ), we get =600 ;k=2 v= k= 6002=300 m/s

$The displacement of a wave travelling in the x direction is y = 10^{- 4} sin (600 t - 2 x + \frac{π}{3}) m, where x is in metre and t in second. The speed of the wave is$
