Question

The resolving power of telescope can be increased by (A) increasing the diameter of object (B) increasing the wavelength of light used (C) decreasing the diameter of objective (D) decreasing the frequency of light used

As we know,
the resolving power of a telescope

= \frac{d}{1.22 λ}

where,

d

is the diameter of objective. So if the diameter of objective lens of telescope is increased then the resolving power will be increase.

Q. The resolving power of telescope can be increased by

increasing the diameter of object

increasing the wavelength of light used

decreasing the diameter of objective

decreasing the frequency of light used

As we know, the resolving power of a telescope =1.22λd​ where, d is the diameter of objective. So if the diameter of objective lens of telescope is increased then the resolving power will be increase.

As we know,
the resolving power of a telescope $= \frac{d}{1.22 λ}$
where, $d$ is the diameter of objective. So if the diameter of objective lens of telescope is increased then the resolving power will be increase.
