Definition: Longitudinal and Transverse Waves

Wave: A disturbance that transfers energy through matter or space, characterized by its wavelength, frequency, and amplitude.
Longitudinal Wave: A wave in which the particle displacement is parallel to the direction of wave propagation, such as sound waves in air.
Compression: The region in a longitudinal wave where particles are closest together.
Rarefaction: The region in a longitudinal wave where particles are furthest apart.
Transverse Wave: A wave in which the particle displacement is perpendicular to the direction of wave propagation, such as waves on a string or electromagnetic waves.
Crest: The highest point of a wave in a transverse wave.
Trough: The lowest point of a wave in a transverse wave.
Wavelength: The distance between successive crests, troughs, compressions, or rarefactions in a wave.
Frequency: The number of waves that pass a given point per second measured in cycles per second, called Hertz (Hz).
Amplitude: The maximum displacement of particles from their rest position, indicating the wave's energy or intensity.
Period: The time it takes for one complete wave cycle to pass a given point, the inverse of frequency.
Wave Speed: The speed at which a wave travels through a medium, calculated as the product of wavelength and frequency.
Medium: The substance or material through which a wave travels.
Mechanical Wave: A wave that requires a medium to travel, such as sound waves or water waves.
Displacement: The distance and direction from the equilibrium position to a point on the wave.
Propagation: The movement or transmission of waves through a medium or space.
Wave Equation: A mathematical formula that describes the propagation of waves through a medium, often expressed as v_wave = $\lambda$ f , where f is frequency, and $\lambda$ is wavelength.
