Light is fundamentally composed of alternating electric and magnetic fields, often described in terms of photons or quanta, wave packets, or energy. It exhibits dual wave-particle properties, characterized by phenomena such as reflection, refraction, dispersion, polarization, scattering, interference, and diffraction. The behavior of light is governed by Maxwell's equations, and it travels at a constant speed, defined by the relationship c = λf, where λ is wavelength and f is frequency. From an electromagnetic perspective, light consists of oscillating magnetic and electric fields that propagate through space.
