12 Questions
What are the main components of Leeuwenhoek's microscope?
A screw for adjusting height, a metal plate as the body, a skewer to rotate objects, and a spherical lens
How does a compound light microscope work in terms of lenses?
The objective lens magnifies and focuses the image inside the body tube, then the ocular lens magnifies it further.
What determines whether a microscope is classified as simple or compound?
The number of lenses it contains.
What is the function of convex lenses in microscopes?
Convex lenses bend light and focus it in one spot.
How do electron microscopes differ from light microscopes in terms of magnification?
Electron microscopes are more powerful, some can magnify up to 1,000,000X.
What is the difference between a Scanning Electron Microscope (SEM) and a Transmission Electron Microscope (TEM)?
SEM produces realistic 3D images of the surface, while TEM produces 2D images of cell parts inside the cell.
What is the function of the Nose Piece in a microscope?
The Nose Piece holds the objective lenses and can be turned to increase the magnification.
How is total magnification determined in a microscope?
Total magnification is determined by multiplying the powers of the eyepiece by the objective lenses.
What is the function of the Diaphragm in a microscope?
The Diaphragm controls the amount of light on the slide/specimen.
Why is the Arm of a microscope used?
The Arm is used to support the microscope when carried.
What is the function of the Stage Clips in a microscope?
The Stage Clips hold the slide/specimen in place on the stage.
What part of the microscope projects light upwards through the diaphragm, the specimen, and the lenses?
The Light Source projects light upwards through the diaphragm, the specimen, and the lenses.
Test your knowledge on the parts of a microscope such as body tube and nose piece, as well as understanding total magnification. Learn about the powers of eyepiece and objective lenses to determine total magnification. Instructor: Roy P. Maribojoc MD.
