The type of microscope is most likely to be used to view the internal structure of a virus is Electron microscopy.
Microscopy allows the origin of an image resulting from the interaction or the formation of an object from objects incident on the sample, giving origin by detector of different signals, providing characteristic information about a sample.
Electron microscopy (EM) has long been used in the discovery and description of viruses. Organisms smaller than bacteria have been known to exist since the late 19th century (11), but the first EM visualization of a virus came only after the electron microscope was developed.
