Why do shorter wavelengths produce clearer image?

assuming that all other variables remain constant, explain why light of shorter wavelength well produce a clearer image than light of longer wavelengths when using a microscope.Why do shorter wavelengths produce clearer image?
The formula for spot size is:





d = (1.22 Lambda x f ) / D





That is... the longer the wavelength (larger Lambda) the larger the spot sizeWhy do shorter wavelengths produce clearer image?
short wavelengths are less subject to distortion and interference
