Hello,
Resolving power of an instrument is the ability to distinguish clearly between two points which are located at a small angular distance .
Resolving power=D/1.22*lambda
D is the diameter of aperture.
As you can see RP is inverserly proportional to wavelenght used and directly proportional to diameter of lens.Hence when wavelenght increases RP decreases and when D increases RP increases.
You can see the link for understanding the topic
Hope it helped.
