Incident Ray makes An angle of 75 degree with the surface of plane mirror .what will be the angle of reflection ????

Dear Student,
Please find below the solution to the asked query:

angle made by the normal = 90-75 = 15o
since angle made by the normal = angle of incidence
Therefore,
i = 15o
according to the law of reflection
i=r
r = 15o

it is obviously 75 degree because angle of incidence = angle of reflection

I think 15 degree because angle of incidence is the angle made by the incident ray and the normal and since given angle is between mirror and ray therefore the other will be 90-angle cause normal is perpendicular
so angle of incidence=angle of reflection=15 degreee
