Study Notes
Definitions and Concepts of Wave Mechanics
- Amplitude refers to the maximum displacement of points on a wave from their rest position, indicating the wave's energy and intensity.
- Crest is the term used for the highest point or peak on a wave, representing the maximum positive displacement.
Types of Waves
- In longitudinal waves, particles vibrate parallel to the direction of the wave's propagation, such as in sound waves.
Interference Phenomena
- Constructive interference occurs when two pulses meet in a way that their displacements add together, resulting in a wave of greater amplitude.
Features of Waves
- A rarefaction is the region of low pressure in a longitudinal wave, where particles are spread apart.
Measurements in Wave Dynamics
- Pulse length is defined as the distance over which a wave pulse travels, measuring the physical extent of the pulse in the medium.
