Study Notes
Wave Propagation
Definition
Wave propagation refers to the process by which energy is transmitted through a medium in the form of waves.
Types of Wave Propagation
- Mechanical Waves: Waves that require a physical medium to propagate, e.g., water waves, sound waves.
- Electromagnetic Waves: Waves that can propagate through a vacuum, e.g., light, radio waves, X-rays.
Characteristics of Wave Propagation
- Speed: The distance traveled by a wave per unit time.
- Frequency: The number of oscillations or cycles per second.
- Wavelength: The distance between two consecutive points on a wave that are in phase.
- Amplitude: The maximum displacement of a wave from its equilibrium position.
Factors Affecting Wave Propagation
- Medium Properties: Density, elasticity, and viscosity of the medium affect wave speed and attenuation.
- Frequency and Wavelength: Higher frequency waves have shorter wavelengths and are more prone to attenuation.
- Obstacles and Boundaries: Reflection, refraction, and diffraction occur when waves encounter obstacles or boundaries.
Applications of Wave Propagation
- Communication Systems: Radio frequency waves are used in wireless communication systems.
- Medical Imaging: Ultrasound and MRI rely on wave propagation principles.
- Seismology: Seismic waves are used to study the Earth's interior.
Mathematical Descriptions
- Wave Equation: A partial differential equation that describes wave propagation in a medium.
- D'Alembert's Solution: A mathematical solution to the wave equation, used to describe wave propagation in one dimension.
