Light And Electron Mircocopes Flashcards
What is the main difference between a light microscope and an electron microscope?
The main difference is that a light microscope uses visible light to illuminate specimens, while an electron microscope uses a beam of electrons.
Which type of microscope has higher magnification capabilities: light microscope or electron microscope?
Electron microscopes have higher magnification capabilities compared to light microscopes.
What is the resolution of a light microscope typically limited by?
The resolution of a light microscope is typically limited by the wavelength of visible light.
What are the two main types of electron microscopes?
The two main types of electron microscopes are transmission electron microscopes (TEM) and scanning electron microscopes (SEM).
Which type of electron microscope is used to observe the surface of specimens in 3D?
A scanning electron microscope (SEM) is used to observe the surface of specimens in 3D.
What is the typical resolution of a transmission electron microscope (TEM)?
The typical resolution of a transmission electron microscope (TEM) is around 0.2 nanometers.
Which type of microscope is commonly used in biology labs for observing cells and tissues?
Light microscopes are commonly used in biology labs for observing cells and tissues.
What is the maximum magnification of a light microscope?
The maximum magnification of a light microscope is typically around 1000x.
What is the advantage of using an electron microscope over a light microscope for studying nanoscale structures?
The advantage of using an electron microscope is that it offers higher resolution and magnification, making it suitable for studying nanoscale structures.
What is the function of the condenser in a light microscope?
The condenser in a light microscope focuses light onto the specimen to illuminate it.
