Microscopes 2

• What’s is maginication?

  The degree to which the size of an image is larger than the object itself.
• What is Resolution?

  The smallest distance between two points that can still be seen as separate entities.(higher resolution enables you to see more detail).
• What is equation that gives you the TOTAL Magnification of an image?

  Total Magnification = Eye piece lens magnification x Objective lens magnification
• What is the equation that gives you the magnification?

  Magnification= Image size /Actual size
• • Total magnification is used to determine how much an object is enlarged when viewed through a microscope or telescope. It helps scientists and researchers observe details that are not visible to the naked eye.
  • Magnification is used to determine how much larger (or smaller) an image appears compared to the actual size of the object.
• Magnification= image size/ actual size

  I = Image size

  A =Actual size

  M =Magnification

• Where does a beam of electron passes through?

  through a very thin slice of the sample
• What can you use a light microscope for?

  You can use a light microscope to observe small structures in detail.
