Question 12 • MS-Physical Science

Which microscope is the most powerful and can map the atoms on the surface of an object?

Answer
A
a classroom compound microscope
B
a transmission electron microscope
C
a scanning electron microscope
D
a scanning tunneling microscope

Explanation

A scanning tunneling microscope can image a surface at the atomic scale and map the positions of individual atoms. It does this by measuring the tunneling current between a tiny probe and the surface. The other microscopes can reveal much smaller structures than a classroom microscope, but they do not map surface atoms in this way.
