microscopy

• light microscopes

  use light and lenses to form an image and magnify it. They let us see individual cells and subcellular structures.
• Disadvantages of light microscopes

  -limited magnification

  -limited resolution so the image is blurred
• electron microscope

  uses electrons to form an image
• advantages of electron microscopes


  -higher magnification

  -higher resolution

  -lets us see much smaller things in more detail
• magnification equation

  magnification= size of image/size of real object

  m=i/o
