Magnification

Magnification

Magnification = Size of an image
                           Actual size

For exampe the question is
*400

1) Make a large diagram of a cell
Ans ) Draw a large diagram of any cell


2) Find Magnification of you drawing
  • First find the length of RBC in cell
  • Suppose x=3 cm
  • Find the actual size of RBC
Magnification= Image size
                          Actual size
400 =        3        
          Actual size
Actual size =   3  
                      400
Actual size = 0.0075
  • find the length of drawn image
  • suppose it is 10 cm
Magnification =    10    
                           0.0075
Magnification = x1333.33

Note:
  • If the magnification is not given ( x400 ) then leave the first step to find the actual size
  • x is necessary to use in the answer of magnification

    Is it necessary to calculate the image size and actual size in millimetres before putting it in the magnification formula ???? Or does it depend on the unit they asked us in the question? ???

      Just reaarange the formula. Actual size=imagesize÷magnification.

    There is also a question after this like how many cell like this could you line up between the two millitre Mark's of your scale
