Reflection of Light
The rebounding back of light rays into the same medium on striking a highly polished surface such as a mirror is called the reflection of light.
Laws of Reflection:
There are two laws of reflection:
- The incident ray, the reflected ray and the normal at the point of incidence all three lie in the
same plane. - The angle of incidence (i) is always equal to the angle of reflection (r).
Types of Reflection:
Regular Reflection
When a parallel beam of reflected light rays is obtained for a parallel beam of incident light rays after reflection from a plane reflecting reflection is called regular reflection.
Irregular or Diffused Reflection
When a non-parallel beam of reflected light rays is obtained for a parallel beam of incident light rays after reflection from a surface, then such type of reflection is called irregular or diffused reflection.
