Question 9 • Biology

Which microscope uses a probe to map atoms on the surface of a specimen?

Answer
A
scanning tunneling microscope
B
compound light microscope
C
scanning electron microscope
D
transmission electron microscope

Explanation

A scanning tunneling microscope uses a very fine probe that moves across a specimen’s surface and detects changes in electrical current to map its atoms. A compound light microscope uses light, while electron microscopes form images using electron beams rather than a surface-scanning probe.
