Question

multiple-choice question
after the two waves pass through each other, ____

they continue on unchanged.

they continue on inverted.

they disappear.

Explanation:

This question is about wave behavior, specifically the principle of superposition and wave propagation. When two waves pass through each other, they interfere temporarily (constructive or destructive), but after passing, each wave continues with its original amplitude, wavelength, and direction—unchanged. The other options are incorrect: waves don’t invert after passing (inversion is related to reflection, not transmission through each other) and they don’t disappear (waves maintain their identity after interference).

Answer:

A. they continue on unchanged.
