Hint: Light can be defined as the form of the electromagnetic radiation with the radiation that can be detected by the human eye. Also, it is the small part of the electromagnetic spectrum and the radiation which is given off by stars like the sun.

Complete answer:
Light is electromagnetic radiation which shows both the properties of waves and particles. It is the form of energy and also keeps the Earth warm. It exists in the form of tiny energy packets known as photons. Each wave consists of the wavelength or the frequency.The human eye observes each of the wavelengths as the different color. For example, rainbows represent the complete spectrum of the visible light.

The main properties of light are:
-Intensity
-Polarization
-Phase
-The orbital angular momentum
Sometimes, in physics the light is considered as the electromagnetic radiation of any wavelength in cases of whether it is visible or not.

Note: In simple words, light is something which makes vision possible. Also, light can be defined as the electromagnetic radiation of any wavelength which travels in the vacuum with the speed and the radiation which is visible to the human eye.
