Here's a breakdown:
* Resolving power refers to the ability of an optical instrument to distinguish between two closely spaced objects.
* A higher resolving power means the instrument can distinguish between objects that are closer together.
* This is determined by the wavelength of light used and the size of the aperture (opening) of the instrument.
* For example, microscopes have a higher resolving power than the human eye because they use shorter wavelengths of light and have smaller apertures.
In simpler terms, resolving power is how well an optical instrument can see detail.
