AB is small object dipped in water at a depth of d. Its length is l. It is seen from air at near normal incidence. The length of the image is:

An object lies 100 cm inside water (mu=4//3) . It is viewed from air nearly normally. Find the apparent depth of the object.

Object AB is placed on the axis of a concave mirror of focal length 10cm. End A of the object is at 30cm from the mirror. Find the length of the image a. if length of object is 5cm. b. if length of object is 1 mm.

Object AB is placed on the axis of a concave mirror of focal length 10cm. End A of the object is at 30cm from the mirror. Find the length of the image a. if length of object is 5cm. b. if length of object is 1 mm.

A small linear object of length I is placed along principal axis of a concave mirror. The neartest point the object is at a distance d from the mirror. If focal length of the mirrors is f then, prove that the size (length) of the image will be l((f)/(d-f))^(2)
