Physics · Wave Motion
The amplitude of a wave disturbance propagating in the positive x-direction is given by y = 1(1 + x)2 at time t = 0 and y = 11 + (x - 2)2 at t = 1 s, where x and y are in metres. If the shape of the wave does not change during propagation, the velocity of the wave will be:
- 14 m/s
- 23 m/s
- 32 m/s✓
- 41 m/s
Correct answer
2 m/s
