Wavelength is the main limiting factor on resolution because the image of two particles cannot be seen individually if it is smaller than the wavelength.
The wavelength of light used to illuminate the object also has an effect on microscope resolution. And how will the wavelength of light affect the magnification of microscope
The visible light range in nanometers ranges from 380nm to 750nm. Another way to change the wavelength is to change the objective lens and the specimen. Light wavelength is inversely related to microscope magnification. The magnification of a microscope reduces as the wavelength rises, and vice versa.
The wavelength of light used to illuminate the object also has an effect on microscope resolution. Longer wavelengths of light have worse resolution than shorter wavelengths. As light slows, the wavelength shortens, resulting in higher resolution.
