(i) Reflection of Light

When light rays strike the boundary of two media such as air and glass, a part of light is turned back into the same medium. This is called Reflection of Light. The wavelength and the velocity of the light wave remains the same.

Laws of reflection are obeyed at every reflecting surface, i.e.

iii) Types of reflection

(a) Regular Reflection

(b) Diffused Reflection or Scattering or Diffusion

(a) Regular Reflection: When the reflection takes place from a perfect plane surface it is called Regular Reflection.

(b) Diffused Reflection or Scattering or Diffusion: When the surface is rough light is reflected from the surface from bits of its plane surfaces in irregular directions. This is called diffusion. This process enables us to see an object from any position.
