Detailed explanation-1: -The branch of physics that deals with the study of the nature and properties of light is called optics.

Detailed explanation-2: -Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light.

Detailed explanation-3: -Optics is the branch of physics that deals with the law and nature of light.

Detailed explanation-4: -quantum mechanics, science dealing with the behaviour of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents-electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.
