Light is a form of energy, which enable us to see the object.
In this chapter we will study the phenomena of reflection and refraction using the
property of light i.e. straight line propagation (Light wave travel from one point to
another, along a straight line).
Reflection of Light
When the light is allowed to fall on highly polished surface, such as mirror, most of
the light gets reflected.
Laws of Reflection
- The angle of incidence is always equal to
angle of reflection.
i = r
- The incident ray, reflected ray and the
normal to the reflecting surface at the
point of incidence lie in the same plane.
