Optic is one of the branch of physics which deals with the light and properties of it. We know that light shows both the particle and wave characteristics. However, in this unit we will learn the particle characteristics of the light. Some of the topics will be covered in this unit are; reflection and refraction of light, plane mirrors, concave and convex mirrors, reflection of light from the mirrors, prisms and behavior of light in different mediums.

Properties of Light

  • Light shows both wage and particle characteristics.
  • It can travel in vacuum and speed of light in vacuum is 300.000.000m/s
  • Light consists of particles which are called as photons.
  • People see objects with the help of light.
  • Light interacts with the matter and according to the types of material it reflects or refracts.
