Magnification and Resolution
To observe biological
material we use microscopes, to know the size of the specimens we can use this
formula:
The triangle above is a easier way to remember and use the formula just put your thumb over the symbol you want to figure out.
Magnification: is the extent
to which a actual size of an object is enlarged into the image seen through a
microscope.
Resolution: is the extent to
which two objects can be distinguished as a separate structure.
A helpful mnemonic would be
to us ''I AM''
Example:
Q. A microscope has a
magnification of X1500 and a RBC has a diameter of 1.05cm what is the actual
diameter?
A. Actual size= Size of
image/Magnification= 1.05/1500=0.0007cm (7um)
