The thickness of the analysis sample used in the Transmission electron microscope is in order of ______ Correct Answer nanometres

In TEM High energy electron beam is passed through the sample. The thickness of the sample where analysis needs to be done should in order of a few hundreds of nanometres. Because the depth is high, electron will not pass through the sample.
