Resolving power of a telescope can be increased by

A

increasing the diameter of the objectie of the telescope

B

decreasing the diameter of the objective of the telescope

C

increasing the wavelength of light

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
R.P. of a telescope `=(D)/(1.22lamda)`
`therefore R.P.propD`
thus R.P. can be increased by increasing the diameter of the objective of the telescope.
