Question
Why can't we see atoms?A) We see with light energy and the wavelength is larger than the object and so it is not reflected.
B) Atoms are invisible.
C) We cannot see things that are microscopic.
D) We see with light energy but the atoms absorb all the light and therefore there are no reflections.
E) Atoms do not interact with light energy and therefore we are unable to observe them with light.
