The semi vertical angle subtended by two points of an object at the objective of a microscope is 30^@ . The object is illuminated using light of wavelength 589.3 nm. Calculate the minimum distance between the two points if these are just resolved. If a medium of R.I 1.48 is used between the object and the objective, then calculate the new limit of resolution. Comment on the improvement in the limit of resolution.
