One end of a cylindrical glass rod (μ = 1.5) of radius 1.0 cm is rounded in the shape of a hemisphere. The rod is immersed in water (μ = 4/3) and an object is placed in the water along the axis of the rod at a distance of 8.0 cm from the rounded edge. Locate the image of the object.


Radius of the cylindrical rod R= 1.0 cm

Refractive index of glass is

Refractive index of water is

Object distance =u= -8 cm

By lens equation

Hence, the image will be formed at infinity.
