Light: Light is a form of energy that enables us to see things. Light starts from a source and bounces off objects which are perceived by our eyes and our brain processes this signal, which eventually enables us to see. Nature of Light Light behaves as a: ray, e.g. reflection wave, e.g. interference and diffraction particle, e.g. photoelectric effect Laws of Reflection Light incident on another medium When light travels from one medium to another medium it either: gets absorbed (absorption) bounces back (reflection) passes through or bends (refraction) When light is incident on a plane mirror, most of it gets reflected, and some of it gets absorbed in the medium. Characteristics of light Speed of light c = λ × μ , where λ is its wavelength and μ is its frequency. Speed of light is a constant which is 2.998 × 10 8 m / s or approximately 3.0 × 10 8 m / s .
