What is Light? Maxwell and the Electromagnetic Spectrum
Guided Notes
3 key concepts
- 1
Classical electromagnetism, which describes light as a transverse wave composed of oscillating electric and magnetic fields, was developed by James Clerk Maxwell in the 19th century.
- 2
Different frequencies of electromagnetic waves produce different kinds of light; visible light corresponds to different colors, while frequencies greater than visible light include UV radiation, x-rays, and gamma rays.
- 3
All electromagnetic radiation moves at the speed of light, which is approximately 300 million meters per second in a vacuum, and the product of a wave's wavelength and frequency is equal to its speed.
