• How do you use a light microscope

  1. Check the microscopes for electrical safety
  2. Click the lowest power objective lense in place
  3. Place a slide on the stage under the objective lens
  4. use the coarse focusing dial to get a focused image
  5. once you have focuses the image, use the fine focusing dial to reveal the detail
  6. repeat 4 and 5 with a higher objective lenses
• Magnification is the ratio of the size of the image to the size of the object.
• resolution is how close 2 objects are together and can still be seen as seperate objects before they blur together and look like one object
• what is the maximum magnification for a light microscope?

  x1500
• What is the maximum magnification for a electron microscope?

  x500,000
• What is the resolution for the light and electron microscope?

  light is 250nm and electron is 0.25nm
• what does a LIGHT microscope use?

  light
• What does a ELECTRON microscope use?

  electrons
• A light microscope focuses by glass lenses
• A electron microscope focuses by electromagnets
• What can we use to look at in a light microscope and what can we look at in a electron microscope?

  Living and non-living things but only with non-living things for a electron microscope
• What is the difference between a light microscope and a electron microscope?

  Light microscope is cheap , easy , small and portable but a electron microscope, its expensive , massive , need to be installed in one place and need to be very trained
• how do you convert cm into mm?

  Multiply the number of centimeters by 10.
• How do you convert mm into micrometres?

  Multiply by 1000.
• how do you convert micrometres into namometres?

  Multiply the value in micrometers by 1000.
• how do you convert namometre into micrometres?

  Divide by 1000.
• how do you convert micrometres to mm ?

  Divide the number of micrometers by 1000.
• how do you convert mm into centimetres?

  Divide the number of millimeters by 10.
• Actual size = image size / magnification
• magnification size = image size / actual size
• image size = actual size x magnification
• To find the actual size of something measured under a microscope you divide its size in the image by the magnification
• Magnification is a degree by which is enlarged
• Resolution is the ability of a microscope to distinguish detail
• what Is this equation triangle for?

  To measure microscopy of an actual size/image size or the magnification
