Microscopy

• What are the advantages of an electron microscope over a light microscope?

  Greater magnification and resolution
• What are the limitations of light microscopes?

  • Limited magnification
  • Limited resolution (blurred images)
• Why are light microscopes not useful for viewing structures inside the nucleus?

  Because their magnification is not powerful enough and the resolution is limited
• What is the formula for calculating magnification?

  Magnification = size of image / size of real object
• How do you calculate the magnification if the image size is 45 mm and the real object size is 0.01 mm?

  4500 times
• How do you calculate the size of the real object if the image size is 87 mm and the magnification is 2000 times?

  • Use the formula: Size of real object = size of image / magnification
  • Calculation: 87 mm / 2000 = 0.0435 mm
• What is the significance of the high resolution in electron microscopes?

  It enables the observation of fine details in cellular structures
• How does the invention of the electron microscope impact the study of cells?

  It allows for detailed exploration of cellular structures
