An incident Ray makes 60 degrees angle with the surface of the plane mirror, what is the angle of refraction. Options are...a 60 b 90 c 30 d 0....this is a question in a guide is it correct

measured to the normal, it will be refraced to the normal, so it will be in the glass, bent toward the normal, so then the q is where is the angle of refraction measured to, and it is normally to the normal, so the angle of incidence was 30, bent to the normal, it has to be less than 30 https://www.google.com/search?q=refreaction+ray+diagrams&ie=utf-8&oe=utf-8
