WebbThe aperture (or more formally entrance pupil) of a telescope is larger than the human eye pupil, so collects more light, concentrating it at the exit pupil where the observer's own pupil is (usually) placed. The result is increased illuminance – stars are effectively brightened. WebbCurrently, the smallest thing that can be seen using a microscope is about the size of an atom. Anything smaller is below the current limit of resolution of the electron microscope, although the microscopic scale is …

The electrons in an atom tend to be arranged in such a way that the energy of the atom is as low as possible. The ground state of an atom is the lowest energy state of the atom. When those atoms are given energy, the electrons absorb the energy and move to a higher energy level. These energy levels of the … WebbMicroscopes enhance our sense of sight – they allow us to look directly at things that are far too small to view with the naked eye.
