Question

Two wave pulses move toward each other along a rope.

Two small triangular crests moving toward each other.
Which diagram shows the resulting wave when they cross at point X?

A straight line.
A triangular crest.
A rectangular crest.
A triangular trough.

GPT-5 mini · Answer

A triangular crest.

Reason: the pulses add by superposition. Two crests interfere constructively at X, producing a larger (triangular) crest (amplitude = sum of the two amplitudes).
