Study Notes
Transverse Waves
Definition
- A type of wave that oscillates perpendicular to the direction of propagation
- The wave's displacement is perpendicular to the wave's velocity
Characteristics
- Amplitude: The maximum displacement of the wave from its equilibrium position
- Wavelength: The distance between two consecutive points on the wave that are in phase with each other
- Frequency: The number of oscillations per second
- Speed: The distance traveled by the wave per unit time
Types of Transverse Waves
- Mechanical waves: Require a physical medium to propagate, e.g. water waves, seismic waves
- Electromagnetic waves: Do not require a physical medium, e.g. light, radio waves, X-rays
Properties
- Polarization: The orientation of the electric field vector in electromagnetic waves
- Reflection: The change in direction of a wave when it hits a surface
- Refraction: The change in direction of a wave when it passes from one medium to another
- Interference: The superposition of two or more waves resulting in a new wave pattern
Real-World Applications
- Communication: Electromagnetic waves are used in communication systems, e.g. radio, Wi-Fi, visible light
- Medical Imaging: Electromagnetic waves are used in medical imaging techniques, e.g. X-rays, MRI
- Seismology: Mechanical waves are used to study earthquakes and the structure of the Earth's interior
