The magnification of a 4 x 12d lens is 48 times
The total magnification is equal to the magnification of the eyepiece multiplied by the magnification of the objective lens. So in this case the objective lens would need to be 100X.
Calculating total magnification is pretty simple. Take the magnification of the eyepiece and multiply by the magnification of the objective. So in this case 10x x 4x = 40x.
The general formula for Total maginifcation Tm is: Tm= Me x Mob where Me is the magnification produced by the eyepiece and Mob is the magnification produced by the objective.
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.
950
the eyepiece lens magnification X the magnification of the objective lens.
The total magnification is equal to the magnification of the eyepiece multiplied by the magnification of the objective lens. So in this case the objective lens would need to be 100X.
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).
To calculate magnification , multiply mag.Power of both lenses 15 x 30 = 350
The total magnification would be 200x, since the total magnification is the magnification of the objective lens X the magnification of the eyepiece.
magnification of the eyepiece X magnification of the lens (depends on which one you choose)
10 X 10 = 100 magnification. Ocular lens = 10 Objective lens = 10
Calculating total magnification is pretty simple. Take the magnification of the eyepiece and multiply by the magnification of the objective. So in this case 10x x 4x = 40x.
10x
10 x 5 = 50 the magnification of microscope is 50
MP=(d/L)*(1-(L-l)f) where d would be the distance from the eye to the image without a lens L is the distance from the eye to the new virtual image (with a lens) l is the distance from the eye to the lens this equation only covers a single lens (whereas there tend to be two in a microscope), but that's no worry; use it twice! (i.e treat both lenses as independent sources of the image)
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
