When a parallel beam of light on striking some smooth and polished surface is reflected as a parallel beam of light such reflection is called regular reflection
when parallel beam of light on striking some rough surface is reflected in some differnt direction ,then such reflection is called irregular reflection
regular reflection is when the beam of light is reflected through a plane surface.
irregular refflection take place when the beam of light is reflected by uneven surface
reflection of light is of two types.one is regular reflection and other is diffused/irregular reflection.regular reflection takes place when reflecting surface is smooth and irregular reflection takes place when reflecting surface is not smooth or uneven.
when reflection takes place from smooth and polished surface and the reflected rays are parellel to each other it is regular reflection.
when reflection takes place from rough and irregular surface and the reflected rays are intersecting it is irregular reflection.
REGULAR REFLECTION IS THE REFLECTION IN WHICH LIGHT RAYS GET REFLECTED UNIFORMLY WHILE IN IRREGULAR REFLECTION THE LIGHT RAYS ARE SCATTERED AFTER REFLECTION.REGULAR REFLECTION TAKES PLACE FROM A WELL POLISHED,EVEN SURFACE WHILE IRREGULAR REFLECTION TAKES PLACE FROM A UNEVEN SURFACE.REGULAR REFLECTION PRODUCES A CLEAR,DISTINCT IMAGE WHILE IRREGULAR REFLECTION PRODUCES A UNCLEAR IMAGE.
