Terms and Definitions
| Objective lens X Ocular lens = | Total magnification | |
|---|---|---|
| For example: | low power: | (10X)(10X) = 100X |
| high dry: | (40X)(10X) = 400X | |
| oil immersion: | (100X)(10X) = 1000X |

| Low power/ scanning | 4x | 40x |
| Medium power | 10x | 100x |
| High power | 40x | 400x |
What is the total magnification of 10X and 40x?
400x magnification A microscope's total magnification is a combination of the eyepieces and the objective lens. For example, a biological microscope with 10x eyepieces and a 40x objective has 400x magnification.
When the high power 40x objective is used the total magnification will be?
When the high power (40x) objective is used the total magnification will be 400x. When the oil immersion (100x) objective is used the total magnification will be 1000x. Which objective lens provides the highest total magnification? The __________ causes the stage to move upward or downward.
What is 40x in microscope?
A 40x objective makes things appear 40 times larger than they actually are. Comparing objective magnification is relative—a 40x objective makes things twice as big as a 20x objective while a 60x objective makes them six times larger than a 10x objective. The eyepiece in a typical desktop microscope is 10x.
What is the highest magnification on a microscope?
The maximum magnification power of optical microscopes is typically limited to around 1000x because of the limited resolving power of visible light. While larger magnifications are possible no additional details of the object are resolved.
What is the total magnification of 10x?
The total magnification is multiplication, so the total is ocular multiplied by objective. So here The ocular is 10 and the objective is 100. So it's 10 times 100 which is 1000. So the total magnification Is 1000 times.
What is the total magnification of low medium high objective lens?
For example, if the ocular lens magnifies the image 4X and the low-power objective lens magnifies the image 10X, the total magnification of the object under low-power is 40X (4 x 10 = 40X). With the same ocular lens and a high-power objective that magnifies 40X, the total magnification would be 160X (4 x 40 = 160X).
What is high power on a microscope?
High power microscopes – also called compound microscopes because of their two-stage magnification – are the 'typical' microscope that is seen in laboratories and on television. High power microscopes typically magnify in the range ×40 to ×1000; much greater than this will only produce fuzzy images with no more detail.
What is the total magnification of 4x?
| Total Magnification: | |
| To figure the total magnification of an image that you are viewing through the microscope is really quite simple. To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X. | |

How much magnification is 40x?
A 40x objective makes things appear 40 times larger than they actually are. Comparing objective magnification is relative—a 40x objective makes things twice as big as a 20x objective while a 60x objective makes them six times larger than a 10x objective. The eyepiece in a typical desktop microscope is 10x.
What is the total magnification of 40x?
400x
| Magnification | Total Magnification | |
|---|---|---|
| Scanning | 4x | 40x |
| Low Power | 10x | 100x |
| High Power | 40x | 400x |
| Oil Immersion | 100x | 1000x |

What is total magnification with a 10x objective?
Low Power Objective (10x) The total magnification of a low power objective lens combined with a 10x eyepiece lens is 100x magnification, giving you a closer view of the slide than a scanning objective lens without getting too close for general viewing purposes. Figure 1.
What is 10X in microscope?
We all know that 10X means that the objective lens has an effective magnification of ten times life size and when combined in the compound with a 10X ocular lens will give a final magnification of 100X (10 X 10).
What is the total magnification of 10x and 4x?
| Total Magnification: | |
| To figure the total magnification of an image that you are viewing through the microscope is really quite simple. To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X. | |

What is the total magnification of a microscope?
Total Magnification: To figure the total magnification of an image that you are viewing through the microscope is really quite simple. To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X.
How do you calculate HPF?
High power fields (HPF) conventionally use the ×40 objective, giving an overall magnification of ×400 with a 10× eyepiece, or ×500 with a 12.5× eyepiece. The area is calculated by πr2, where “r” is the radius (half the diameter) of the field of view.
What is the total magnification of 4X?
| Total Magnification: | |

What is the 4X objective lens called?
Scanning Objective Lens (4x) Its name, the 'scanning' lens, derives from the fact you are zoomed-out enough that you can scan around your specimen at this magnification level to prepare to move on to higher magnifications. Using this objective, aim to: Achieve focus using the coarse focus knob.

What do you mean by HPF in physical education?
A high-power field (HPF), when used in relation to microscopy, references the field of view under the maximum magnification power of the objective being used. Often, this represents a 400-fold magnification when referenced in scientific papers.
