2.1.1: Microscopy Basics Flashcards
What is the resolution of a microscope?
The minimum distance between two objects in which they can still be viewed as separate.
What determines the resolution in an optical microscope?
The wavelength of light.
What determines the resolution in an electron microscope?
The wavelength of the beam of electrons.
What is magnification in the context of microscopy?
How many times larger the image is compared to the object.
Name the four key types of microscopes.
- Light microscopes
- Transmission electron microscopes
- Scanning electron microscopes
- Laser scanning confocal microscopes
True or False: Light microscopes can provide a color image of living samples.
True
What is a limitation of light microscopes?
They have a poor resolution due to the long wavelength of light.
