JEE Main 2012 Physics question
The disturbance y(x, t) of a wave propagating in the positive x-direction is given by at time t = 0 and by at t = 2 s, where x and y are in meters. The shape of the wave disturbance does not change during the propagation. The velocity of wave in m/s is
Answer: (3)
Solution
The pulse peak moves from x = 0 to x = 1 m in 2 s without changing shape, so the speed is 0.5 m/s, option (3).
