Question

whats the definition of optics?

Answer 1

Answer:

Like all the different types of light, the spectrum of visible light is absorbed and emitted in the form of tiny packets of energy called photons. These photons have both the properties of a wave as well as a particle.

Hence this type of property is called wave-particle duality and the study of light in the area of physics is known as Optics.
