Microscopes
Microscopes are used to look at things that are not visible to the naked eye. This category would demonstrate how microscopes work and information about different kinds of microscope.

What should be done when ever you are finished using a microscope?
Remove the slide or sample. Turn off the lamp or light source. Turn off power at power point. Gently wind down the higher magnification to the stop position. Clean the objective lens if oil was used ( to stop the oil oxidising on the lens). Cover the microscope to protect from dust. Carry with two hands, one under the base, the other on the neck or column. Store away from heat, light and moisture.

Is a microscope what enlarge an object 400 times is to have resolution of 400?
No. The resolution states how close two points can be, while you can still distinguish them as distinct points. A greater enlargement - making something look 400 times larger - may or may not help to improve the resolution. (An exaggerated enlargement may make the image larger, but blurry.)
What two optical devices use convex lenses to focus and enlarge images?
An optical microscope or twlescope.
Who was the person that produced the first compound microscope?
The first compound microscope is generally credited to Hans Lippershey, a Dutch spectacle maker, in the early 17th century. However, it was later developed and improved by other scientists, notably Galileo Galilei, who built his own version in 1609. The design and functionality of microscopes evolved significantly over time, integrating contributions from various inventors.
Where is your password for scanning?
I'm sorry, but I cannot assist you with that. It's important to keep your passwords secure and private. If you're having trouble with password management, consider using a password manager for safe storage.
What are the advantage and disadvatges of a light microscope?
The advantages and disadvantages of the light microscope relate to light, magnification and resolution. Light microscopes magnify visible light--an obvious advantage, since this is what our eyes can see. Magnification (how large an object appears) and resolution (the clarity of details) are both limited when using light microscopes.
What can you put on a specimen to make it easier to see through the microscope?
phenyle blue was a common dye used in biology when I was in college. You need to check to see what the particular item you are wanting to look at will react with first, though.
How many microscopes did Anton van Leeuwenoek make?
Anton van Leeuwenhoek invented a method for making small spherical lenses that much increased the magnification of simple (one lens) microscopes. The magnification of 250 times and possibly greater was ten times better than compound microscopes at the time.
Beyond the initial discovery of the method for making small spherical lenses, van Leeuwenhoek built microscopes and experimented with their design and use. In the process, he made important new discoveries of microscopic life.
Over a period of nearly 50 years, he made over 500 optical lenses (though they did not necessarily go into 500 different microscopes) and can be said to have constructed at least 25 variations on the basic design of the microscope. Nine of his microscopes still exist.
How does 4x on the low power equal 40 x on the microscope?
The objective lens (right above the slide stage) is 4x. The eyepiece (what you look into) is 10x. 4 times 10 = 40. Whatever the objective lens power is, you have to multiply it by the eyepiece power (usually 10x) to get the overall magnification.
How should you first focus on a specimen when using the microscope?
start by focusing with the lowest lens to make sure the slide is right and you can see the specimen them proceed to the next lens power and focus again just to make the view clear then proceed to the highest and focus one more time
What wheel do you use on a microscope to make the image clearer?
To make the image clearer on a microscope you can use the focusing lens.
What is the total area you see when you look into a microscope?
That would depend on the magnification you are using.
What are the names of the 2 lenses of the microscope?
The two main lenses of a microscope are the objective lens and the ocular (or eyepiece) lens. The objective lens is located near the specimen and typically has varying magnifications, while the ocular lens is situated at the top and is what the viewer looks through to see the magnified image. Together, they work to enhance the detail visible in the specimen being observed.
Why do start with low power on a microscope?
On where you start is totally optional, but it is most beneficial to start on the lowest power, so that you can adjust your magnification from then on to make out the object your trying to see. Start low then work your way to high.
What is the magnifying power of the eyepiece used?
That depends on the eyepiece, a 9mm eyepiece will have more magnification than a 22mm eyepiece.
