Question

Hello people ~

Resolving power of telescope can be increased by increasing
(a) the wavelength
(b) the diameter of objective
(c) the diameter of eyepiece
(d) the focal length of eyepiece​

Answer 1

The diameter of the objective

Step-by-step explanation:

Let's see how?

• Resolving power be R

• Diameter be d
• Wavelength be lambda

`\\ \rm\rightarrowtail R=(d)/(1.22\lambda)`

Hence

`\\ \rm\rightarrowtail R\propto d`

• So if d is more R is more
