Question
An infinitely long rod lies along the axis of a concave mirror of focal f. length f. The near end of the rod is at distance u > f from the mirror the mirror. Its image will have a length -
Options
A.
B.
C.
D.
Solution
u = - u, f = - f vA =
Image of last end of rod vB = - f
Length = vB - vA = - f -
= 
Length =
