Light waves are electromagnetic radiation that's visible to the human eye. It is the energy that allows us to see the world around us. Light waves move at different frequencies and wavelengths, which give them different colors.

Wave-Particle Duality: The idea that light behaves as both a wave and a particle. The wave nature of light explains phenomena such as interference, diffraction and polarization, while the particle nature of light explains the photoelectric effect. Frequency: The number of wave cycles per second of a wave, measured in hertz. The frequency of light determines its color, with higher frequency light having shorter wavelengths and thus a higher energy. Amplitude: The maximum displacement from the equilibrium position of a wave, measured in decibels. The amplitude of light determines its brightness, with higher amplitude light having higher energy.

Light waves can travel through a vacuum, which is a space with no air particles. Light waves move faster in a vacuum than when they are in air. The speed of light is 299,792,458 meters per second, which is the fastest speed in the universe.
