It introduces wavelength, amplitude, and frequency, relating wave speed to λ×ν, then treats light as electromagnetic radiation governed by Maxwell’s concepts. The electromagnetic spectrum is linked to radiation wavelength, while Planck’s quantum hypothesis and the equation E=hν motivate discrete energy exchange.
