What is the dual character of light?

Light exhibits a dual character as both a wave and a particle, a concept known as wave-particle duality. As a wave, it demonstrates behaviors such as interference and diffraction, which are characteristic of wave phenomena. Conversely, as a particle, light is composed of photons, discrete packets of energy that can exhibit particle-like interactions, such as in the photoelectric effect. This duality is fundamental to quantum mechanics and helps explain various phenomena in physics.
