Which is a difference between a compound light microscope and a scanning electron microscope?

A.The scanning electron microscope can view the internal part of a cell, while the compound light microscope views the surface of a cell.
B.The scanning electron microscope specimens can be stained for contrast, while the compound light microscope specimen appears black and white.
C.The scanning electron microscope is used for dissections, while the compound light microscope is not.
D.The scanning electron microscope uses an electron beam and a layer of gold to view the surface of the cell, while the compound light microscope uses light and lenses.

Answer:

The answer is D.The scanning electron microscope uses an electron beam and a layer of gold to view the surface of the cell, while the compound light microscope uses light and lenses.

Explanation:

Electron microscopes use an electron beam instead of a light beam to form an image, so they can only offer black and white images; while the compound microscope is based on optical lenses, which is also known as a light microscope; It has a lens system that focuses the light from the source towards the small point of the specimen.

The difference between a compound light microscope and a scanning electron microscope is: D. The scanning electron microscope uses an electron beam and a layer of gold to view the surface of the cell, while the compound light microscope uses light and lenses.

A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object in order to reveal all the littlest information about the object that cannot be seen by the natural human eye.

Generally, there are different types of microscopes and these include;

  • Inverted microscope.
  • Polarizing microscope.
  • Compound light microscope.
  • Scanning electron microscope.

A compound light microscope refers to an upright microscope that has more than one lens and a visible light source to enlarge an image of a small object.

On the other hand, a scanning electron microscope is a type of microscope that is designed to have a focused high-energy electron beam and a layer of gold to scan the surface of a specimen.

In conclusion, difference between a compound light microscope and a scanning electron microscope is that the former uses light and multiple lenses while the latter uses an electron beam and a layer of gold to view the surface of a specimen.
