A Electron 10 μm Q microscope B Fluorescence microscopeYou are in charge of buying new microscopes for your company, and you have been comparing different types of microscopes. One important property for microscopy is the resolution, which measures the ability to distinguish two small objects that are close together. Rank the following list of microscopes from lowest to highest resolution. Microscope List (5 items) (Drag and drop into the appropriate area) Transmission electron microscope (uses high energy electron beam) X-ray microscope (uses x-ray absorption to image sample, range 0.01-10 nm) Confocal fluorescence microscope (uses a blue laser as a light source, 488 nm) Level of Resolution 2 Lowest
