what be the greatest visual magnification ahieved with normal kind microscopes like compound type?
that be 1000x. but how you can determine this for any microscope?
what be the depth of field? and what power be depth of field the smallest?
what power an object be the biggest?
i try helping my sister with this someone please explain everything i check all website and not real understand.
normal limit now is 1500x
How do you determine? Measure something of known scale and compare.
depth of field: Depth of field is independent of magnification, it is related to aperture http://en.wikipedia.org/wiki/Depth_of_field
What power an object be the biggest? The largest power.
for limit 1500x does it not say on objective lenses? is there no other way to determine?
but wont object be biggest on low power because u be able to see all of it and not only one part of it? cause on question sheet it say what power object be biggest (careful)
If you're looking at a single cell, it will be larger with the higher power.
ok thank you bobpursley and ms. sue :)
You're welcome, Mohammad.
The greatest visual magnification achieved with normal compound microscopes is typically around 1000x. However, it is important to note that the maximum achievable magnification depends on different factors such as the quality of the microscope's optics and the observer's visual acuity.
To determine the maximum magnification of any microscope, you need to consider the magnification power of the objective lens and the eyepiece lens. The objective lens is located near the sample and provides the primary magnification, while the eyepiece lens is positioned at the eyepiece of the microscope and further enhances the magnification.
To calculate the total magnification, simply multiply the magnification power of the objective lens by the magnification power of the eyepiece lens. For example, if the objective lens has a magnification of 40x and the eyepiece lens has a magnification of 10x, the total magnification would be 400x (40x multiplied by 10x).
Now, let's discuss the concept of depth of field. In microscopy, the depth of field refers to the distance between the nearest and farthest points that appear in focus at the same time. A shallow depth of field means that objects in front of or behind the focused plane appear blurry, while a deep depth of field means that a larger range of objects appear in focus simultaneously.
The power of the objective lens determines the depth of field. Generally, lower-power objective lenses provide a larger depth of field, while higher-power objective lenses have a shallower depth of field. For example, a 4x objective lens would have a larger depth of field than a 40x objective lens.
Lastly, regarding the size of the object, the magnification power of the objective lens determines how large the object appears under the microscope. Higher magnification power leads to a larger magnification of the object, allowing for more detailed observation. However, it's important to remember that higher magnification levels can also lead to a trade-off in terms of the depth of field, as mentioned earlier.
I hope this explanation helps you understand these concepts and assist your sister in her studies. Remember, always refer to credible sources and consult with experts to ensure accurate information.
