Solution
The correct option is A 90°
Given that the angle of incidence is 45°.
We know by the law of reflection, angle of incidence = angle of reflection.
Therefore, the angle of reflection is 45°.
Now, from the above image we can say that the angle between the reflected ray and the incident ray = angle of incidence + angle of reflection.
= 45° + 45°
= 90°
