Q. The resolving power of telescope can be increased by
UPSEE
UPSEE 2019
A
increasing the diameter of object
75%
B
increasing the wavelength of light used
0%
C
decreasing the diameter of objective
0%
D
decreasing the frequency of light used
25%
Solution:
As we know,
the resolving power of a telescope $ = \frac {d}{1.22\lambda}$
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.
