Define resolving power of a microscope .

The expression of resolving power of a microscope is inversely proportional to the wavelength lambda used to illuminate the object . Can we have a source with a very small wavelength compare to that of the visible light ?

The resolving power of a microscope, with a pair of non-luminous objects is

What is meant by limit of resolution and the resolving power of microscope ?

Derive an expression for Resolving Power of a Microscope.

Discuss the resolving power of a microscope:-With luminous point objects.

Derive an expression for resolving Power of a Telescope.

What is meant by limit of angular resolution and the resolving power of telescope ?

The resolving power of a telescope of aperture 100 cm for light of wavelength 5.5 xx 10^-7 m is

The vertical angle subtended by two points on a glass block at the objective of a microscope is 20^@ .Calculate the minimum distance between the points if they are just resolved when illuminated by light of wavelength 600 nm. What is the increase in resolving power of the instrument if the objective is immersed in oil of refractive index 1.5?

Assertion : Stars are often photographed with the help of telescope fitted with a blue filter. Reason : Blue filter transmits blue light. Which has shorter wavelength. Therefor, resolving power of telescope increases.
