Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

What is the equation to work out overall magnification from eyepiece magnification and objective lens magnification?

A	Overall= Objective x Eyepiece
B	Overall= Objective/Eyepiece
C	Overall= Eyepiece/Objective
D	None of the above

Explanation:

Detailed explanation-1: -You must multiply the eyepiece magnification with the objective magnification and then divide the field number. If the eyepiece states 10x/18 and the magnification of the objective lens is 40, then the total magnification will be 10 x 40 = 400.

Detailed explanation-2: -To calculate the total magnification of a microscope, simply multiply the power of the ocular lens by the power of the objective lens. For example, if the ocular lens is 5X and the objective lens is 12X, the total magnification would be 5 x 12 or 60X.

Detailed explanation-3: -The angular magnification of the eyepiece is given by the relation me=1+dfe, where me is the magnification of the eyepiece of the microscope, d is the least distance of vision and fe is the focal length of the eyepiece., where v0 is the image distance, u0 is the object distance.
