Write the expression for limit of resolution of a) Microscope and b) Telescope. Write on method increasing the resolving power of microscope.

Explanation

a) For microscope
limit of resolution, dx `=(1.22lambda)/(2n sin theta)`
b) For telescope,
limit of resolution, `d theta=(0.61lambda)/(a)`
The resolving power of microscope can be increased,
1. By using a medium of higher refractive index surrounding the object and microscope.
2. By using light of shorter wavelength.
