Two wave pulses travel in opposite directions on a string and approach each othe

Question

Two wave pulses travel in opposite directions on a string and approach each other. The shape of one pulse is inverted with respect to the other.

Options:

A . The pulses will collide with each other and vanish after collision.

B . The pulses will reflect from each other, i.e., the pulse going towards right will finally move towards left and vice versa.

C . The pulses will pass through each other but their shapes will be modified.

D . The pulses will pass through each other without any change in their shapes after the overlap.

Answer: Option D
:
D
The shapes of wave pulses after the overlap are identical to their original shapes.
After overlap each pulse travels just as it did before.
