Microscopy and magnification: Cell biology: Biology

• Light microscope


  Equipment which uses visible light to detect and magnify small objects

  
• Electron microscope


  Equipment which uses electron beams to produce images with higher magnification and resolution

  
• Magnification


  How much an image appears to have increased in size by

  
• Resolution


  The degree of detail visible in an image

  
• Magnification equation


  Magnification = size of image/size of real object
