Light exists in tiny energy packets called photons.Light is electromagnetic radiation that shows properties of both waves and particles. Light is a form of energy.Light also keeps the Earth warm. Light exists in tiny energy packets called photons. Each wave has a wavelength or frequency. The human eye sees each wavelength as a different color. Rainbows show the entire spectrum of visible light. The separate colors, moving in from the outer edges, are usually listed as red, orange, yellow, green, blue, indigo and violet. Other colors can be seen only with special cameras or instruments: Wavelengths below the frequency of red are called infrared, and higher than of violet are called ultraviolet.
The other main properties of light are intensity, polarization, phase and orbital angular momentum.

Answer:
Light is a form of electromagnetic radiation with a wavelength which can be detected by the human eye.[1] It is a small part of the electromagnetic spectrum and radiation given off by stars like the sun. Animals can also see light. The study of light, known as optics, is an important research area in modern physics. When light hits an opaque object it forms a shadow but when the light hits a transparent object, it passes through it almost completely without producing a shadow.

In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.[2][3] This article is about visible light. Read the electromagnetic radiation article for the general concept.
The law of reflection is what allows us to see an object reflected in a mirror.
