Remember that the magnification will be less than 50X since that is the maximum that can be attained with the dissecting scope. A total magnification of 100x requires the use of the 10x ocular lens with which of the objective lenses? You can magnify the image and move around to see the magnification engraved on each lens. The magnification of the ocular lens of a microscope is x10 and the magnification of the objective lens for low, medium, and high power are 4X, 10X, and 40X, respectively. The objective lens points down toward the object to be magnified. The ocular lens is also named as “eyepiece”. The ocular lens are 10x magnification. 5. In the science of optics, the magnification of an object like a lens is the ratio of the height of the image you can see to the height of the actual object being magnified.

Also keep in mind that the total magnification of any image you see through the ocular lens is the product of the objective and ocular lens magnifications (for example, when using the lower power lens the total magnification is: 10X ocular x 10X low power objective = 100X). The optical power of the eye-piece ranges between 7x and 15x. The total magnification of 40 means that the object appears forty times larger than the actual object. How is a mutation in a bacterial cell that deletes three base pairs 10 base pairs upstream from the + 1 site likely to affect transcription and why? A typical ocular is 10x.
