The angle formed between the reflected ray and the normal is ______.
Angle of incidence is greater than the angle of reflection.
Diffused reflection gives a sharp image.
Assertion (A): A ray incident along normal to the mirror retraces its path.
Reason (R): In reflection, the angle of incidence is always equal to the angle of reflection.
