The focal length of the main optical system and the focal length of the lens forming the image.
it would be 15 times 40 which is 600 times magnification
10*100 = 1000 times.
One can calculate the total magnification of a microscope by multiplying the magnification of the eye piece by the magnification of the main scope. For a compound microscope one must multiply each eye piece magnification.
x means the magnification times. 10x means it is magnified 10 times.
you must multiply the two lenses getting a total of 150X
Multiply the magnification or power of the objective lens times the power of the eyepiece and it equals the total magnification
Field diameter of lens B equals field diameter of lens A times total magnification of lens A divided by total magnification of lens B
The total magnification is the object magnification for example 4x,10x etc. times eyepiece magnification usually 10x and you get the total magnification. The objective lens magnification is the lens right above the slide usually 4x,10x etc.
it would be 15 times 40 which is 600 times magnification
The total magnification of the microscope when using the 40x objective depends on the strength of the eye piece lens. Typically a 10x eye piece lens is used in college microscopes this would give 40x10 = 400x magnification.
To quote Wikipedia;"The angular magnification is given by : :: : where Mo is the magnification of the objective and Me the magnification of the eyepiece." So 10x X 20x = 200x
Total magnification is calculated by objective times ocular lens. So if you increase the objective lens is directly related to an increase in magnification.
Each objective lens has a different magnification. Multiply the magnification of the eyepiece by the magnification of the objective lens to produce total magnification. For example, a 10X ocular lens and a 40X objective lens will produce a total magnification of 400X (10 x 40 = 400).
15 * 30 = 450 ------------
Magnification of objective multiplied by magnification of eyepiece. I usually work with 40x and 60x ojectives and 10x eyepiece, so total magnifications of my observations are respectively 400 and 600 times.
Total magnification means enlarging something in terms of appearance to the full extent. This is the measure of how many times bigger something can get compared to actual size.
To determine the magnification of the eyepiece on a microscope take the total magnification for the microscope and divide it by the total magnification of the objective lens. The answer is what the magnification is for the eyepiece.
