Question

List three types of specimens a dissecting microscope might be used to view.

Answer 1

1. Simple optical microscope. One lens.
Disadvantage: Only Van Leeuwenhoek made them, and he's dead.
Advantage: Worked pretty well. With them, Van Leeuwenhoek discovered protozoa and bacteria.

2. Compound optical microscope. Has both an ocular and objective lens.
Disadvantage: limited resolution. Can resolve bacteria, but not smaller things like viruses.
Advantage: can be used with live specimens (using phase contrast or polarized or other special illumination).

3. Binocular dissecting microscope (optic). Has a pair of ocular and objective lenses, and supposedly presents a "3D" view of the specimen to the viewer (I was never able to see in 3D using these darn things).
Disadvantage: Limited magnification
Advantage: Can be used to perform surgery on small but not microscopic specimens, such as fruit flies. Is used in "microsurgery" in hospitals too.

Hope this helps buddy!

Answer 2

The three types of specimens a dissecting microscope are as follows:

1. Optical Microscopes.
2. Electron Microscopes.
3. Scanning Probe Microscopes.

• Optical microscopes are the oldest and the simplest microscope it uses a single convex lens to enlarges the image placed under its focus.

• Electron Microscope is used by scientists to study cell, this microscope fire beams of electrons on the subject which is held in the vacuum-sealed tubes.

• Scanning probe microscopy is a powerful microscope, it can detect matters smaller than the nano-meter however its images have no color because it uses probe measure things other than visible light.
