Subtopic: Reflection by Spherical Mirrors

A light ray traveling parallel to the principal axis of a concave mirror strikes the mirror at angle of incidence q. If radius of curvature of the mirror is R, then after reflection, the ray meets the principal axis at distance d from the centre of curvature, then d is 
R/2
\[\frac{R cos\theta}{2}\]
\[\frac{R}{2cos\theta}\]
\[\frac{R}{2}(1+cos\theta)\]
