When using a 10X ocular and a 15X objective and the field size is 1.5 mm the approximate field size with a 30X objective is what mm?
0.75 mm
way to get this answer...........
(diameter of field A X total magnification of field A) / total magnification of field B
so start by finding the diameter of field A= which is the 1.5
next figure out what the total magnification of field A is= 150 (you get this answer by multiplying the ocular # which is 10x by the objective # which is 15x.
(10 x 15= 150)
next figure out what the total magnification of field B is =300 (you get this answer by multiplying the ocular # which is 10x by the other higher objective # which is 30x.
(10 x 30 = 300)
then you can use the formula and plug in all the answers you got to get the answer
(1.5mm x 150)/300=.75mm

What is the total magnification of an object observed through a 65x objective with a 10x eyepiece?
450x TM ( magnification of the ocular lens ( 10x) multiplied by the magnification from the objective lens ( 45x)= 450x TM ( total magnification)
What is the maximum magnification of the dark-field microscope?
The maximum magnification of a dark-field microscope typically ranges from 400x to 1000x. This level of magnification allows for detailed observation of specimens with enhanced contrast due to the dark-field illumination technique.
Why don't microscope makers use 100x ocular lenses?
Microscope makers typically do not use 100x ocular lenses because it can lead to image distortion, reduced field of view, and decreased depth of field. Using lower magnification ocular lenses ensures a better balance between magnification and image quality for most microscopy applications.
What is used to focus when using the scanner and low objective?
When using the scanner and low objective on a microscope, you should use the coarse focus knob to bring the specimen into approximate focus and then use the fine focus knob to achieve a sharp image. Adjusting the height of the stage may also be necessary to fine-tune the focus.
Which objective scanning low power or high power allows you to observe the greatest number of cells within the field of view?
Scanning a specimen using a low-power objective allows you to observe the greatest number of cells within the field of view. Low-power objectives have a lower magnification but a wider field of view compared to high-power objectives, enabling a broader view of the specimen.

When using a microscope with a 10x ocular and the 40x objective plane what is total magnification?
400x
What is the magnification of a microscope with an ocular eye piece of 10X and an objective of 50X?
The total magnification would be 500x...you take the ocular and multiply it by whatever objective you are using.
Why is it necessary to calibrate the ocular micrometer with each objective?
The ocular micrometer is inside the ocular lens, it will not change size when the objectives are changed. Therefore, each objective lens must be calibrated separately. Ocular micrometers have no units on them - they are like a ruler with marks but no numbers. In order to use one to measure something under a microscope, you must assign numbers to the marks. This is done by looking through your OCULAR micrometer at a STAGE micrometer mounted on a slide. The stage micrometer is just a ruler with fixed known distances, so you can use it to tell how far apart marks are on the ocular micrometer. This has to be done because the marks on the ocular micrometer are different distances apart depending on the magnification used on the microscope. It must be calibrated for each objective.
What is the total magnification of an object observed through a 65x objective with a 10x eyepiece?
450x TM ( magnification of the ocular lens ( 10x) multiplied by the magnification from the objective lens ( 45x)= 450x TM ( total magnification)
Is there more or less light passing through the ocular lens when using the higher power objective lens compared to the low power why?
Less light

When scanning 4 times objective is Used the total magnification will be?
When using a 4x objective lens on a microscope, the total magnification is calculated by multiplying the objective lens magnification by the eyepiece magnification. If the eyepiece (ocular) lens is typically 10x, the total magnification would be 4x (objective) × 10x (eyepiece) = 40x. Therefore, when scanning with a 4x objective, the total magnification will be 40x.
What is a sentence using the word ocular?
Ocular has to do with the eyes. It is usually an adjective, but it is considered an eyepiece in its noun form. For example. Your eyes exist in your ocular cavity.
How to determine the total magnification when using any objective of your microscope?
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.
What is the highest possible magnification that can be obtained when using a microscope?
Objective - Ocular 40 x 10 = 4000x
