Question
This picture is of ________.
- Compound microscope
- Light microscope
- Phase contrast microscope
- Electron microscope
Hint:
- An electron microscope is comprised of two magnifying lens systems, a condensing lens, specimen holder, electron gun, and a focusing apparatus. The electron microscope is mainly used to observe the internal structure of cells and the ultrastructure of surfaces.
The correct answer is: Electron microscope
- The common light microscope used in the laboratory is called a compound microscope because it contains two types of lenses that function to magnify an object.
- A light microscope is an optical instrument used to view objects too small to see with the naked eye. It is so-called because it employs the use of white or visible light to illuminate the object of interest so it can be magnified and viewed through one or a series of lenses.
- Phase contrast is a light microscopy technique used to enhance the contrast of images of transparent and colorless specimens. It enables visualization of cells and cell components that would be difficult to see using an ordinary light microscope.
- An electron microscope is a microscope that uses a beam of accelerated electron as a source of illumination.
- An electron microscope is comprised of two magnifying lens systems, a condensing lens, specimen holder, electron gun, and a focusing apparatus. The electron microscope is mainly used to observe the internal structure of cells and the ultrastructure of surfaces.
- So we can say above picture is of electron microscope.
