  • Cell Yourself - Microscopes
    • LIGHT MICROSCOPES
      • CELLS ARE STUDIED IN MORE DETAIL USING MICROSCOPES
        • ELECTRON MICROSCOPES
          • USES ELECTRONS NOT LIGHT TO FORM IMAGE
            • STANDARD FORM
              • THE FIRST NUMBER NEEDS TO BE BETWEEN 1 AND 10 SO E.G. 0,0025, DECIMAL NEEDS TO GO AFTER 2 THEN COUNT HOW MANY DECIMAL PLACES IT HAS TO MOVE = 2.5 X 10 TO THE POWER OF 3
            • HAS A HIGHER MAGNIFICATION, RESOLUTION THEN LIGHT
              • RESOLUTION- THE DEGREE TO WHICH IT IS POSSIBLE TO DISTINGUISH BETWEEN 2 OBJECTS THAT ARE VERY CLOSE TOGETHER
              • MAGNIFICATION - THE DEGREE TO WHICH THE SIZE OF AN IMAGE IS LARGER THEN THE IMAGE ITSELF.
                • MAGNIFICATION = IMAGE SIZE/REAL SIZE
                  • REARANGE FORMULA, FILL IN VALUES, CONVERT FROM MICROMETERS.
      • USES LIGHT AND LENSES TO FORM AN IMAGE OF A SPECIMEN AND MAGNIFY IT
        • WHEN PREPARING A SLIDE, ADD A DROP OF WATER, PEEL LAYER IF NEEDED, ADD IODINE DROP TO STAIN SO IT ADDS COLOUR AND ADD A COVER SLIP TO THE TOP
          • CLIP SLIDE ON TO STAGE, SELECT LOWEST POWERED OBJECTIVE LENS, USE COARSE ADJUSTMENT KNOB TO MOVE STAGE UP, LOOK DOWN EYEPIECE AND USE COARSE KNOB UNTIL IT'S FOCUSED AND ADJUST WITH FINE FOCUSING KNOB
