Answer 2

$\huge\mathcal\fcolorbox{pink}{azure}{Answer♡}$If the angle between the incident ray and reflected ray is 90°, the angle of reflection is half of 90° i.e., 45° . Always, the angle of incidence = the angle of reflection. This means that the angle which the normal makes with the incident ray is the same as the angle which the normal makes with the reflected ray. The angle between the incident ray and the reflected ray would be the sum of the angle of incidence and the angle of reflection, both of which are equal. Therefore is 90° is twice the angle of reflection here.
