Question

draw ray diagram when an object is placed 8cm from the pole of a convex mirror​

Answer 1

Answer:

Answer

a. object is placed at 30 cm from the

mirror.

Here focal length PF = 15 cm

Object distance PC = 30 cm

PC = twice the focal length = 2×15

When the object is placed at 30 cm from pole i.e. at the centre of curvature, an incident ray parallel to principal axis reflects at mirror and passes through the focus, Second ray of light passing through focus reflects at mirror and passes parallel to the principal axis. These both reflected ray DA’ and EA’ meet at a point A’. We draw A’B’ perpendicular to the principal axis which is the real and inverted image of the object.

Image is of same size as object.

A’B’ = -AB

Image distance v = 30 cm
