Question

A rays is incident at an angle 38° on a mirror. The angle between normal and reflected ray is
1) 38° 2) 52° 3) 90° 4) 76°

Answer 1

The angle between normal and reflected ray is:-

90°-38° =52°

Answer 2

$\underline{\huge {\mathcal{\purple{A}\red{n}\blue{s}\pink{w}\red{e}\purple{r}}}}$

As per the question,rays are falling on mirror , which cleared that Regular reflection is taking place.

So, As per the laws of regular reflection.

$\implies \angle{incident } = \angle{reflection }$

$\angle{incident }=\angle{reflection }= 38°$

Also we know that normal is at 90°to the mirror.

Now ,To get the required angle we need to reduce angle of reflection from normal.

$\implies \rm 90° - 38° = 52°$

So , 2) 52° is the correct answer.
