A sharp image is formed when light reflects from a smooth surface.
What is reflection?
A reflective image is formed when light bounces off a reflective surface.
Reflective images can be sharp or blurred depending on the surface on which the light rays bounce from.
When the surface is rough, blurred images are formed. On the other hand, sharp images are formed from smooth surfaces. Sharp images are formed by mirrors because they have smooth surfaces.
