The Wave Equation from Maxwell's Equations
Inside this lesson
- Derive the electromagnetic wave equation from Faraday's law and the Ampère-Maxwell law in source-free vacuum
- Identify the wave speed c = 1/√(μ₀ε₀) and compute its numerical value
- Explain why this result implies that light is an electromagnetic wave
- Calculate the wavelength of an EM wave given its frequency
