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?
Most go up to 1000x as it is light field microscopy. The ocular lens (the one that you look into) is 10x, but there are different objectives to focus on the specimen that you rotate to chose. The lowest is usually 4x, then 10x, 40x, and then 100x. Multiply ocular lens (10x) X objective lens you are using (ex: 40x) = Total 400x Oil immersion drop is used ONLY on the 100x objective.
Why important to start focusing the lowest power objective?
You use the low power objective lens first to get your sample centered in the field of view.
Why reduce your light when using 10x objective lens?
You would reduce your light when using the 10x objective because it will reduce eye discomfort and will increase contrast.
What is the total magnification of a microscope with a 10x Eyepiece and a 40x Objective?
The total magnification of the microscope when using the 40x objective depends on the strength of the eye piece lens. Typically a 10x eye piece lens is used in college microscopes this would give 40x10 = 400x magnification.
What the difference between objective lens and the ocular lens when using a microscope?
the name
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.
When using a microscope with a 10x ocular and the 40x objective plane what is total magnification?
400x
What is the highest possible magnification that can be obtained when using a microscope?
Objective - Ocular 40 x 10 = 4000x
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
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.
What are the advantages of using low power objective for initial viewing?
To locate the exact site in the microscope field that you want to magnify.
How would you estimate the size of object viewed under high power objective lens 40 times if you were given the size of the field diameter when using low power objective lens 4 times?
the naswe is 400
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.
Can you give a sentence using objective?
Please clarify your objective with an example.
