it has to do with the resolution of the image of the slide obtained...the larger the objective lens value is the greater the resolution it will provide, greater the resolution higher the details.
40 because you have to multiply the ocular lens times the objective lens and the ocular lens is almost always 10x i think. Hopefully it is in your case. I know our microscopes are like that. Hope this helps! :)
The objective lens magnifies the specimen, producing a real image that is then magnified by the ocular lens resulting in the final image; The total magnification can be calculated by multiplying the objective lens value by the ocular lens value
To set up a microscope follow these steps:Hold the microscope by its base.Place it near a light source. (Not directly in the sun.)Adjust the mirror until light is reflected up the microscpe. (Check this by looking done the microscope.)Turn the objective lens to its lowest magnification.
Total magnification with a low power objective lens is calculated by multiplying the magnification power of the objective lens by the magnification of the eyepiece (ocular lens). Typically, a low power objective lens has a magnification of 10x or 4x, and when combined with a standard 10x eyepiece, the total magnification would be 100x or 40x, respectively. Therefore, total magnification for low power objectives usually ranges from 40x to 100x.
depends which microscope ur using..... the strongest (not NASA's) is about 1,000x The definition of magnification power is given by the relationship: Magnification = 250 mm / f Thus, a 25-mm focal-length positive lens would be a 10x magnifier.
no lens is changed!
The magnification of the eyepiece lens in a microscope is typically 10x. This means that when combined with the magnification of the objective lens, the total magnification of the microscope is calculated by multiplying the magnification of the eyepiece by the magnification of the objective lens.
The total magnification of a microscope is determined by multiplying the magnification of the objective lens by the magnification of the eyepiece lens. For example, if the objective lens has a magnification of 10x and the eyepiece lens has a magnification of 20x, the total magnification would be 10x * 20x = 200x.
The total magnification of a compound microscope is calculated by multiplying the magnification of the eyepiece lens by the magnification of the objective lens. In this case, with a 10x eyepiece lens and a 20x objective lens, the total magnification would be 10x * 20x = 200x. Therefore, the total magnification of the microscope is 200x.

The magnification of a compound light microscope is determined by multiplying the magnification of the ocular lens (eyepiece) by the magnification of the objective lens. For example, if the ocular lens has a magnification of 10x and the objective lens has a magnification of 40x, the total magnification would be 10x * 40x = 400x.
The smallest magnification lens on a compound light microscope is the scanning objective lens, typically with a magnification of 4x.
The total magnification of a compound microscope is calculated by multiplying the magnification of the objective lens by the magnification of the eyepiece. So, total magnification = magnification of objective lens x magnification of eyepiece.
To calculate the total magnification of a microscope, you multiply the magnification of the objective lens by the magnification of the eyepiece. For example, if the objective lens has a magnification of 40x and the eyepiece has a magnification of 10x, the total magnification would be 40x * 10x = 400x.
The total magnification of a light microscope with a 40x objective lens is calculated by multiplying the magnification of the objective lens by the magnification of the eyepiece lens. Assuming a standard eyepiece magnification of 10x, the total magnification would be 400x (40x objective lens * 10x eyepiece lens = 400x total magnification).
Simply, multiply the magnification of the ocular lens times the magnification of the objective lens you have in place.
