Which of the Following is NOT True of a Transmission

Question

Which of the following is NOT true of a transmission electron microscope (TEM)?
A) The limit of resolution is about 0.1μm.
B) Electrons are passed through the specimen.
C) It gives the clearest three-dimensional images.
D) The specimen must be fixed in plastic.
E) The electron beam is focused with electromagnets.

Accepted Answer

TEM does not provide three-dimensional images; it produces high-resolution, two-dimensional images. Scanning electron microscopes (SEM), not TEM, are known for giving clear three-dimensional images.
