The light rays gets reflected in the same angle. Angle between normal and the incident ray is called angle of incident and angle between normal and reflected ray is called angle of relection. Normal is an imagenary perpendicular line on the reflecting surface. Angle of incidence is alway equal to angle of reflection.
When light strikes a smooth surface (like a mirror), it is reflected. When it hits a rough surface (like a sheet of paper) it is diffused, meaning the rays of light are scattered.
If the surface is shiny then you might get an image on a screen. If the surface is transparent as well then refraction well also take place.
Otherwise the image formed will be blurred and mostly distorted. That is why we expect the surface of the mirror to be optically plane. Hence smooth.

When light strikes a rough surface it reflects in essentially random directions.
If the surface is shiny then you might get an image on a screen. If the surface is transparent as well then refraction well also take place.

When a sound wave strikes a smooth hard surface the wave bounces off. This means that the wave is deflected.
Specular reflection occurs when light bounces off of a smooth surface such as a mirror!
it is because a mirror has a smooth surface.
