The branch of physics dealing with the properties and behaviour of light is called Optics. Light is a form of energy which helps us to see the objects. Have you ever wondered why we are able to see the different objects around us, their images in a mirror, in a pond? This is simply due to reflection of light . It is the phenomenon of bouncing back of light after striking a smooth polished surface.
