Study Notes

Wave Basics

A wave is a vibration or disturbance that travels from one point to another and carries energy.
Wave propagation refers to the movement of waves.

Wave Characteristics

All waves have frequency, amplitude, wavelength, and wave speed.
Wave speed is quantified by the equation v = f × λ, where v is the wave speed in meters per second (m/s), f is the frequency in hertz (Hz or 1/s), and λ is the wavelength in meters (m).

Factors Affecting Wave Speed

Tension affects wave speed in a cord, with increased tension resulting in faster wave speeds.
Mass per unit length of a cord also affects wave speed, with increased mass resulting in slower wave speeds.
Rigidity and density of a medium affect the speed of sound waves, with higher rigidity and lower density resulting in faster speeds.
Temperature affects the speed of sound, with higher temperatures resulting in faster speeds.

Wave Categorization

Waves can be categorized based on the presence or absence of a medium for propagation.
Mechanical waves (e.g. sound waves) require a medium to propagate.
Electromagnetic waves can propagate with or without a medium.

Wave Types

Transverse waves are characterized by vibrations perpendicular to the direction of wave propagation.
Longitudinal waves occur when vibrations are parallel to the direction of wave propagation.
