Standing Waves

Flashcards covering the concepts of standing waves, their formation, characteristics, and energy perspective as described in the lecture notes.

Under what condition can the net horizontal displacement of waves become zero?

The waves have moved again to produce a net horizontal displacement of zero.

What are the corresponding frequencies for allowed standing waves on a fixed-length string?

Fn=nv/2L

How does a standing wave transport energy?

A standing wave appears to stand in place; energy does not flow past the nodes and remains localized in the string.

How does a traveling wave transport energy?

A traveling wave oscillates in place, transports energy, and moves.

How are standing waves formed?

Standing waves arise from the superposition of incident and reflected waves and form when an incident wave reflects and interferes with itself in the same medium.

What are the characteristics of the incident and reflected waves that form a standing wave?

They come from the same source and have the same frequency, wavelength, and amplitude.

What are nodes in a standing wave?

Nodes are points of zero displacement.

What are antinodes in a standing wave?

Antinodes (loops) occur midway between nodes with maximum displacement.

What is the distance between adjacent nodes (Ax) in a standing wave?

Ax = lambda/2
