Question

For a telescope, larger be diameter of the objective lens : (A) greater the resolving power (B) smaller is the resolving power (C) greater is the magnifying power (D) smaller is the magnifying power

Tardigrade Admin · Accepted Answer

Resolving power of telescope =(d/1.22λ ) So, for telescope having larger the diameter of the objective lens, will have more resolving power.

Q. For a telescope, larger be diameter of the objective lens :

greater the resolving power

smaller is the resolving power

greater is the magnifying power

smaller is the magnifying power

Resolving power of telescope $= \frac{d}{1.22 λ}$ So, for telescope having larger the diameter of the objective lens, will have more resolving power.

Q. For a telescope, larger be diameter of the objective lens :

greater the resolving power

smaller is the resolving power

greater is the magnifying power

smaller is the magnifying power

Resolving power of telescope =1.22λd​ So, for telescope having larger the diameter of the objective lens, will have more resolving power.

Resolving power of telescope $= \frac{d}{1.22 λ}$ So, for telescope having larger the diameter of the objective lens, will have more resolving power.
