What is the proper definition of light?

Answer Posted / Arpana Bajpai

Light is a form of electromagnetic radiation that exhibits wave-like properties and is visible to the human eye. It consists of photons, which are particles with zero mass and electric charge, but they possess energy proportional to their frequency. The wavelength (λ) and frequency (ν) of light are inversely related by the speed of light (c), such that c = λ*ν.
