Diffraction attenute the resolution of distant objects

In 1st point discuss about angular width of airy disc.

Calculation of resolving power.

How diffraction attenuate the resolution.

Diffraction attenuate the resolving power of telescope

First of all we consider, not only the size of slit width is important for diffraction but the aperture of the lens is also important.

The angular width of airy disc is affected by slit width i.e.by the aperture of the lens.And then resolving power depends upon diffractio
