In physics, normal is defined as the perpendicular that is drawn to the reflecting surface.The radius of curvature of a spherical mirror is the radius of the circle of which the spherical mirror is a part. It can also be defined as the distance between the centre of curvature of the mirror and the pole of the mirror on the principal axis. The radius of curvature is also a measure of how curved the mirror is.

Answer:
Normal= typical, usual or ordinary; what you expect
प्रतिनिधिक, सामान्य या साधारण, औसत; जिसकी आशा हो, प्रत्याशित
the radius of a circle which touches a curve at a given point and has the same tangent and curvature at that point.
