Resolving Power Of Microscope


Advertisements

Description:

Microscope

For better Microscope it should have a higher resolving power. For higher resolving power, dmin should be smaller.

Microscope

dmin =  
1.22λ/2μsinβ

  • For smaller dmin, Sinβ should be greater, i.e., β should be greater, i.e., focus of the microscope should be smaller.

  • For smaller dmin, λ should be small and for small λ, we need to pass the light through liquid with high refractive index μ.

The resolving power of a microscope is

Resolving Power =  
1/dmin

Resolving Power =  
2μsinβ/1.22λ

Telescope

Minimum angle of resolution for telescope is −

dθ =
1.22λ/D

Resolving power of telescope is −

R.P =  
D/1.22λ
