Question

Write the relation between object distance image distance and focus of a convex mirror . what is the relation between radius of curvature and focus of a mirror . how far an objects should be placed from the concave mirror of focal length 3m in order to obtain an image on the screen 9m away from the mirror.

Answer 1

in a convex mirror, the principal focus remains constant. so,the uis directly proportional to the v.so if the object distance increases the image distance also increases.let f be the focal length. so f=R/2.(Ris the radius of the curvature).alsou=-9/2.by the mirror formula

Answer 2
