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.

• 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 1

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

The shapes of wave pulses after the overlap are identical to their original shapes.

After overlap each pulse travels just as it did before.
