Question

Which of the following statements about transmission electron microscopy is FALSE?

1) The sample is placed in a vacuum.
2) Electrons are the source of illumination.
3) Thin segments must be used.
4) Glass lenses are used.
5) Stains can be applied to improve contrast.

Answer 1

The FALSE statement about transmission electron microscopy is that glass lenses are used.

Step-by-step explanation:

Out of the statements provided, the FALSE statement about transmission electron microscopy is: 4) Glass lenses are used.

A transmission electron microscope (TEM) uses electrons as the source of illumination, not light.

Additionally, a TEM requires thin segments of the sample to be used, and the sample must be placed in a vacuum. Stains can also be applied to improve contrast in TEM images. However, glass lenses are not used in a TEM.
