WebThe ability of a telescope to gather light is determined by the mirror’s area. Modern reflecting telescopes use primary mirrors with diameters of up to 10m. The diameter of the primary mirror determines how much electromagnetic radiation the telescope can collect, but it does not determine the power of magnification of the telescope. http://electron9.phys.utk.edu/optics421/modules/m3/telescopes.htm
