short history of light

Newton argued that light acts like a stream of tiny particles moving in straight lines, and reflects off mirrors like a ball bouncing off a wall. But Thomas Young and the Frenchman Augustin Fresnel established another theory, that light is a wave: that light can bend around edges and spread out through two slits in a screen to cause an interference pattern. The wave theory of light became the classical description. Later, experiments showed that light, possessed properties of waves and properties of particles. Evidence can be shown, both experimental and theoretical, for light as a wave and light as a particle.
