Nodes
Definition
Nodes are points in a wave where there is no displacement or amplitude. They occur when two waves interfere destructively, resulting in cancellation of their amplitudes.
Analogy
Think of nodes as spots on a jump rope where it doesn't move up or down when someone is shaking it vigorously. These spots represent points where there is no vertical motion due to destructive interference between waves.
Related terms
Wavelength: Wavelength refers to the distance between two consecutive nodes (or antinodes) in a wave.
Standing Wave: A standing wave occurs when two waves with equal frequency and amplitude traveling in opposite directions interfere constructively and form stationary patterns.
Harmonics: Harmonics are multiples of the fundamental frequency produced by vibrating objects, such as strings or air columns.
