Study Notes
Electromagnetic Waves
- Electromagnetic waves are produced by accelerating charged particles
- Electric field and magnetic field are perpendicular to each other and the direction of wave propagation
- Electromagnetic waves are transverse waves
- All electromagnetic waves travel at the speed of light (approximately 299,792,458 m/s or 3 × 108 m/s) in a vacuum
- Speed of propagation formula: v = fλ, where v is the speed of propagation, f is the frequency, and λ is the wavelength
Electromagnetic Spectrum
- Electromagnetic waves are arranged from longest wavelength to shortest
- Radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, gamma rays
- Different parts of the spectrum have different applications (e.g., radio waves for communication, x-rays for medical imaging)
- Ionizing radiation (gamma, UV, x-rays) have higher frequencies and shorter wavelengths, and higher energy
Reflection of Light
- Reflection is the bouncing back of light after striking a surface
- Angle of incidence = Angle of reflection
- Incident ray, normal (line perpendicular to the surface), and reflected ray lie on the same plane
- Reflection from smooth surfaces is called regular reflection
- Reflection from rough surfaces is called diffuse or irregular reflection
