The scanning tunneling electron microscope uses a probe to measure voltage differences across the surface of a specimen. The specimen may be a small, nearly flat surface. A computer tracks the movement of the probe and creates a three-dimensional image of the specimen. The image allows you to see the location of individual atoms. This was not possible with older microscopes. What is an advantage offered by the scanning tunneling microscope?
A) It measures voltage differences.
B) It uses a probe to scan an object.
C) It allows imaging at the atomic level.
D) It requires a computer.
Ans: C) It allows imaging at the atomic level.
