How do you calculate actual specimen size from magnification and image size?
|
|
Actual = Magnification / Image Size
|
|
|
Actual =Image Size / Magnification
|
|
|
Actual = Image Size x Magnification
|
|
|
None of the above

Explanation:
Detailed explanation-1: -Magnification = image size / actual size. Actual size = image size / magnification.
Detailed explanation-2: -Estimating the Size of the Specimen Under Observation To estimate the size of an object seen with a microscope, first estimate what fraction of the diameter of the field of vision that the object occupies. Then multiply the diameter you calculated in micrometers by that fraction.
Detailed explanation-3: -Cell size can be measured using an eyepiece graticule . The graticule has a scale ruled on it. You must find out the distance measured for each division of the graticule. You can then use the graticule to measure cells.
