Q. A glass sphere having the refractive index (3/2) is having a small irregularity at its center. It is placed in a liquid of refractive index 43 such that surface of the liquid is r high above sphere where r is a radius of a sphere. If the irregularity is viewed from above normally, the distance is 26/K cm from the center where the eye will observe the irregularity. Then find the value of K. (r = 20 cm)
