Understanding Electromagnetic Radiation
Wavelength (λ) is the distance between consecutive peaks of a wave.Frequency (f) is the number of wave cycles per second. They are related by the equation: λ × f = c, where c is the speed of light (299,792,458 m/s).
Photon Energy (E) is the energy carried by a single photon, calculated using Planck's equation: E = h × f, where h is Planck's constant (6.6261e-34 J⋅s).
The Electromagnetic Spectrum:
- Radio waves (km to cm): TV, radio broadcasting
- Microwaves (cm to mm): Microwave ovens, radar
- Infrared (mm to 780 nm): Heat, night vision
- Visible light (780 nm to 380 nm): What we see
- Ultraviolet (380 nm to 10 nm): Sunburn, sterilization
- X-rays (10 nm to 0.01 nm): Medical imaging
- Gamma rays (< 0.01 nm): Nuclear radiation
