Light is a form of energy, which gives us the power of vision. In this chapter we will study the phenomena of reflection and refraction using the property of light i. Ray of light : It is a line in the direction of movement of light. Beam of light : It is bucnh of rays of light. Parallel beam : All the rays are parallel.

Properties of images formed by a plane mirrors: i The image formed by a plane mirror is virtual and erect. Properties of the image formed by a convex mirror: i This image is always virtual and erect. Laws of refraction of light: The refraction of light obeys the following two laws: First law: The incident ray, the refracted ray and normal to the surface of separation at the point of incidence, all lie in the same plane.

Reflection of Light: The phenomenon of bouncing back of light into the same medium by the smooth surface is called reflection. Reflected light: Light which goes back after reflection is called reflected light. Spherical Mirror: If the reflecting surface is part of the hollow sphere then the mirror is a spherical mirror. The spherical mirror is of two types:. Linear Magnification: This is the ratio of the height of the image to the height of the object.
