Question

the ratio of resolving power of a telescope for two different objective lens of diameter d1 and d2 respectively is​

Answer 1

Answer:

wavelength of light decreases

Resolving power of telescope  RP=  

1.22λ

a

​

 

where a is the diameter of objective lens and λ is the wavelength of light.

⟹ RP ∝  

λ

1

​

 

Thus resolving power of telescope increases when wavelength of light is decreased.
