Question

what is the first law of reflection

Answer 1

The First Law of reflection States that the angle made by the incident light ray with the normal to the surface at the point of incidence is equal to angle made by the reflected light ray with the normal.

Answer 2

                     FIRST LAW OF REFLECTION::

Its simple and easy

The first law of reflection states that:
The the ray of light falling on the mirror ( the incident ray )and the reflected ray  and the normal are on the same plane here the  angle f reflection and the angle of incident would be the same

ANGLE OF REFLECTION = ANGLE OF INCIDENCE

DIDN'T UNDERSTAND??/
Practical observation always helps take a mirror and torch in a dark room , incident the torch in some direction you would observe the reflected ray and imagine a perpendicular line between then , observe something>?? they all are on the same plane they dont go hookie dookie allover the place....this is what the first law of reflection states , THE PERFECT AND EQUAL ANGLES BETWEEN THEM MAKES THEM PERFECT SO THIS PROVES THAT ANGLE OF INCIDENE= ANGLE OF REFLECTION -------------- THIS IS THE 1ST LAW OF REFLECTION
