Text Solution

Verified by Experts

The correct Answer is:
(A)-p (B)-p (C)-s (D)-r


(A) Convex mirror `implies` Real object `rarr` virtual image between focus pole
(B) We can see from (v-u) graph, the image distance v between pole & focus for all position of real objects.
(C) `v_(ix) = -m^(2)v_(0_(x)) , v_(ix) = ((f)/(f-x))^(2)u`
`v_(ix) = ((R)/(R-2x))^(2)u , x rarr "object distance"`
(D) Mirror is convex.
