Which type of microscope gives a 3-dimensional view of the specimen?

Question

A. Scanning tunneling microscope

B. Transmission electron microscope

C. Nuclear Magnetic resonance microscope

D. Compound light microscope

Answer 1

A. Scanning tunneling microscope

this creates a view of the surface of an object, showing shape and height, this is a 3d image.

It's like feeling your way across the sample, you can detect height of the specimen. This allows you to detect the shape of whatever you're observing, but not what it's made from.

Why it's not the other answers:

B uses a beam of electrons that passes through a very thin slice of a specimen, allowing you to something of the material makeup and outline of the slice, so it's a flat 'photograph'

C detects the magnetic resonance of the specimen, allowing you to detect the material makeup of a sample, but not the height, it produces a flat image.

D  is basically the same as a regular optical microscope.
