an apaque sphere of radius a is just immersed in a transparent liquid . Apoint sourse is placed on the vertical diameter of the sphere at a distance a/2 from the top ofthe sphere . one ray originating from the point source after refraction from the air liquidinterface forms tangent to the sohere. The angle of refraction for that particular ray is 30° .findthe refractive index of the liquid. .
