Webb30 maj 2024 · The resolving power of an objective lens is measured by its ability to differentiate two lines or points in an object. The greater the resolving power, the smaller the minimum distance between two lines or points that can still be distinguished. The larger the N.A., the higher the resolving power. How do I calculate resolving WebbTelescopes enhance our ability to see distant objects in a number of ways. First, they can gather more light than our eyes. Second, with the help of an eyepiece, they can magnify an image. Lastly, they can help distinguish objects that are close together. This last enhancement is called a telescope's resolving ...
