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.
