A biconvex thin lens of radius of curvature R is made up of variable refractive index 21 Assume d very small aperture 2d R A point object O is placed at a distance R 7 5 m on the principal axis from the lens as shown Due to variable refractive index of lens there are infinite numbers of image on the principal axis These image are spreaded over the length 1 Find the value of 1 in m R A P RR
