Light as a Wave

Light exhibits wave-like properties as electromagnetic radiation, traveling as oscillating electric and magnetic fields. This wave nature explains phenomena like interference, diffraction, and polarization.

Wave Properties

Speed of Light

c=3×108 m/sc = 3 \times 10^8 \text{ m/s}

Wave-Particle Relationship

c=fλc = f\lambda

where:

  • c is speed of light
  • f is frequency
  • λ is wavelength
