The numerical aperture of the objective lens is a measure of its ability to collect light, and it is also inversely proportional to the wavelength of the light. Therefore, higher numerical apertures result in better resolution.<\/p>\n<p>The resolution limit of an electron microscope is typically about 0.1 nanometers, which is about 100 times better than the resolution of a light microscope. This allows electron microscopes to image objects that are too small to be seen with a light microscope, such as individual atoms and molecules.<\/p>\n<p>Option A: 2 V is not a valid answer. The resolution limit of an electron microscope is not measured in volts.<\/p>\n<p>Option B: 1 A.V is not a valid answer. The resolution limit of an electron microscope is not measured in amperes.<\/p>\n<p>Option C: 1.5 A.V is not a valid answer. The resolution limit of an electron microscope is not measured in angstroms.<\/p>\n<p>Option D: 1.2 A.V is the correct answer. The resolution limit of an electron microscope is typically about 0.1 nanometers, which is about 100 times better than the resolution of a light
