Q73. The profile of a wave at time t = 0 and at t =1 sec with A = l cm, B = 1 cm and V2 cm sec is shown in figure. The wave can be represented by the expression (a) y= Ae Blr-w} (b) y= Ae Blr+u} (c) y= Ae B(r-vwXr+v) (d) y=AeBlx-v}r+vr) 1.5 t=1secC t=0 0.5 20 XCm
Option B is correct. You can check the direction of propagation of wave for any given equation of wave, by just looking at the argument (phase). Go through the solution. Best regar...
answer is option B , as the wave is moving in left direction , and option is b is for left moving wave , option a is for right moving , and option c and d are for standing waves. h...
