🌊 What are Electromagnetic Waves?

Electromagnetic waves are oscillating electric and magnetic fields that propagate through space at the speed of light (3 × 10⁸ m/s).

Key Properties:

  • Wavelength (λ): Distance between two consecutive peaks
  • Frequency (f): Number of oscillations per second
  • Amplitude: Maximum displacement from equilibrium
  • Speed (c): c = λ × f
