Question

A node is a point on a standing wave that has no displacement from the rest position.

At the nodes, _____.


there is complete destructive interference between the incoming and reflected waves

there is complete constructive interference between the incoming and reflected waves

the wave is diffracted

the wave is refracted

Answer 1

At the nodes, **there is complete destructive interference between the incoming and reflected waves**.

Nodes occur where the waves align such that their amplitudes cancel each other out, resulting in no net displacement at those points.
