magnification= ocular power *objective power=10X*60X
Ask a jellyfish yea.....well if you don't have a jellyfish around when you need it, you can also look at the magnifier, so if a regular microscope has 4x under lwo power, it is 40x, due to 10x already when you look through the ocular piece. so medium power is 10x, would be 100 times magnified, and 40x for high is 400 times magnified.
The magnification of a telescope is calculated by dividing the focal length of the telescope by the focal length of the eyepiece. In this case, the magnification would be 3000 mm (telescope focal length) divided by 15 mm (eyepiece focal length), which equals a magnification of 200x.
When using a 100X objective lens, you typically want to use a high numerical aperture (NA) condenser lens to match the high NA of the objective lens. A condenser with a NA value equal to or greater than the NA of the objective lens (typically around 1.4) is recommended for optimal resolution and contrast in microscopy.
The limit of resolving power of a microscope is described by the Abbe criterion: d=wl/NA d being the minimal resolvable distance between two spots of the object wl being the wavelength of the light used NA being the numerical aperture of the microscope, which is equal to n*sin(a) with n being the refraction index of the immersion liquid between object and objective a being the aperture angle because sin(a) is always smaller than 1 and n cannot rise above 1.7, the maximal resolving power of a microscope is about d=wl/2 and thus only depends on the wavelength of the light used, which normally will be about 600 nm.
The main lens or mirror produces a virtual image of the obect being looked at, and it occurs at a distance behind the lens (or in front of the mirror) equal to the focal length. The telescope also has an eyepiece whose function is to allow the oberver to see the virtual image. Many telescopes come with a range of different eyepieces that give different amounts of magnification.
The magnification in a microscope is the same for both length and width measurements when using the same objective lens. The magnification factor is determined by the combination of the objective and ocular lenses in the microscope, resulting in equal magnification for both dimensions.
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.

multiply the magnification of the eyepiece by the magnification of the high objective lens. for example, if the eyepiece magnifies x10, and the high objective magnifies x40, then the total magnification would be 400x
1 ocular micrometer scale is equal to 1micrometer when it is seen from 10X objective it will be magnify by 100 times so, 1 ocular micrometer division become 0.1mm ( 1um * 100 = 0.1mm)
If the focal lengths of the objective and eyepiece are equal,then the magnification is ' 1 '.
The objective lens (right above the slide stage) is 4x. The eyepiece (what you look into) is 10x. 4 times 10 = 40. Whatever the objective lens power is, you have to multiply it by the eyepiece power (usually 10x) to get the overall magnification.
lenses: set up or arranged so that when one lens is changed for another, there is no change in focus. * Applied usually to turret mounted lenses e.g. on microscope; also in telescopes: ~ eyepieces: changing one for another does not require refocusing. * When the distance from the object to the rear principal plane of each lens is equal, they are said to be parfocal.
Yes, the magnification of an optical system is equal to the size of the image divided by the size of the object. Magnification describes how much larger an object appears through the optical system compared to its actual size.
