1. Longitudinal Waves
Definition and Characteristics
Longitudinal waves are a type of mechanical wave that involves the oscillation of particles in a medium parallel to the direction of wave propagation. They are characterized by alternating regions of compression and rarefaction, where the medium is alternately compressed and expanded.
Examples of longitudinal waves include sound waves in air, pressure waves in fluids, and seismic waves in the Earth’s crust.
Key Characteristics of Longitudinal Waves, Longitudinal wave gizmo answer key
- Wavelength:The distance between two consecutive points of maximum compression or rarefaction.
- Frequency:The number of oscillations per second, measured in Hertz (Hz).
- Amplitude:The maximum displacement of the particles from their equilibrium position.
2. Gizmo Simulation
