Part A Scanning and tunneling electron microscopes are used to measure high resolution scientific images. As a general rule the wavelength of the electrons must be at least as small as the item being scanned in order to detect/image the presence of the item. The new novel coronavirus has a size of 60 nm to 140 nm. The crowns or "corona" which are the protien like structures that extend from the body of the virus and have a length of 7 nm to 10 nm. The image above was taken at Rocky Mountain Laboratories in Montana, USA, using a tunneling electron microscope (TEM). What approximate size of wavelength was used to produce the image? 0 160 nm 80 nm 20 nm O 5 nm Submit Request Answer Part B What minimum electron speed would be required by a tunneling electron microscope (TEM) in order to detect'image a single coronavirus? (use 3 significant figures) ΑΣ m/s Submit Request Answer - Part What minimum electron speed would be required by a tunneling electron microscope (TEM) to detect/image the length of a single spike which forms the corona" (or crown) of a coronavirus?
