One doubt in concave mirror, when object is virtual,forms real image. Whereas in convex mirror, virtual object forms virtual image only why ?

Ray diagram.... draw and see

Ok

Concept to be noted is that-

  1. Intersection of incident rays is OBJECT and Intersection of reflected rays is IMAGE.
  2. A virtual object on concave mirror is formed when converging rays fall on it and it gets reflected thus point of intersection of incident rays is virtual but point of intersection of reflected rays is real thus according to the first point VO produces RI in concave.
    Same could be followed for Convex.
    Point of intersection of incident rays is virtual and point of intersection of reflected rays is also virtual for convex.
