Question

Compare and contrast light microscopes, scanning electron microscopes, and transmission electron microscopes. Sort each statement into the correct box. Some statements may apply to more than one type of microscope. Some statements may not be used

Answer 1

Answer:

Light microscope, scanning electron microscopes and transmission electron microscopes have several similarities as well as differences.

Explanation:

1. Light microscopes make use of visible light while scanning electron microscopes and transmission electron microscopes makes use of electrons. Scanning electron microscopes use scattered electrons while transmission electron microscopes use electrons transmitted through the sample.

2. Since electrons are used scanning electron microscopes and transmission electron microscopes require vacuum for their working. Hence they cannot be used to analyze living samples. Light microscopes doesn’t require vacuum for their working and hence can be used to study living samples.

3. Scanning electron microscopes are used to observe the surface of specimen while transmission electron microscopes are used to make a ‘through the’ specimen analysis. This makes the specimen preparation for each of the microscopes different. Transmission electron microscope requires thin specimens while scanning electron microscope doesn’t practically require any specimen preparation.
