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.

Why is blue light used to view tiny objects in an optical microscope?
Blue light is used in optical microscopes to view tiny objects because of its shorter wavelength compared to longer wavelengths like red light. The shorter wavelength of blue light allows for higher resolution and better contrast when viewing small structures or details in microscopic samples. This makes blue light ideal for revealing fine details and enhancing image clarity in microscopy.
Anton van leeuwenhoek's microscope?
Short Answer:
The compound microscope was invented 40 years before Anton van Leeuwenhoek was born.
Anton van Leeuwenhoek invented a method for making small spherical lenses that much increased magnification of simple microscopes. He discovered single celled microorganisms and other microscopic structures. He advance the design of the simple microscope.

Anton van Leeuwenhoek, (October 24, 1632 -- August 26, 1723) is known as "the Father of Microbiology". He was from Delft, Netherlands. He was not trained in science, but was originally a tradesman.
The date is not know precisely, but around 1670, more than half a century after the discovery of the microscope, van Leeuwenhoek discovered a way to make small lenses of very high magnification that went significantly beyond the capability of existing microscopes.
He is considered to be the first microbiologist because of his scientific discoveries made possible by his enhanced microscopes. He was the first person to observe and describe single celled organisms. He was a contemporary of Robert Hook and the two men share some credit for establishing that living things were made of cells.
Beyond the initial discovery of the method for making small spherical lenses, van Leeuwenhoek built hundreds of microscopes and experimented with their design. He made over 500 optical lenses (though they did not necessarily become 500 different microscopes) and can be said to have built at least 25 variations on his basic design of the microscope.
What is the correct microscope procedures?
Which of the following is a correct procedure for the operation of a microscope?
First, put the specimen into focus using a low power lens, then switch to a lower power lens if needed.Remove and add slides while the high power lens is selected.First, put the specimen into focus using a low power lens, then switch to a higher power lens if needed.Use the fine focus knob with the low power lens and use the coarse focus knob with the high power lens
it would be 15 times 40 which is 600 times magnification
Which lens should you use to first look at a slide on a microscope?
You should start with the lowest magnification lens, typically the scanning lens (4x or 5x), to locate and center the specimen on the slide. This allows you to get a general overview of the slide before increasing the magnification with higher-power objectives.
What advice would you give to someone to collect light to shine into the microscope?
You should say him/her not to directly take sunlight for the microscope to shine because it will damage your eyes
Why should you always remember when you use the coarse adjustment knob?
Start low, and adjust UP. Otherwise you are in danger of moving the lens DOWN into the slide, breaking the slide, and maybe damaging the lens. Do not ask me how I learned this- OK?
What are the uses of microscopes?
A microscope is a device which helps us to see very minute things, such as micro-organisms, which would normally be far too small to see with the naked eye. They do this by magnifying images on small trays under lenses and a light.
There are many types of microscopes available, but we mostly use optical microscopes in the school or college laboratory.
What are functions of microscopes?
Microscopes are instruments that uses lens to produce magnified images of objects too small to be seen by the eye.

Which objective allows you to see the largest area of the object you are viewing in the microscope?
40x
What part of the microscope should a student turn to obtain a clearer image under high power?
Fine Adjustment knob
When you see something clearly down a microscope it is in what?
When you see something clearly down a microscope, it is in focus. This means that the object being observed appears sharp and clear, indicating that the microscope is accurately magnifying and resolving the image. Adjustments to the focus are made by manipulating the fine focus knob on the microscope to achieve optimal clarity.
What is a microscope in science?
There is a compound light microscope, an scannignn electron microscope, and transmission electron microscope.
its really good question that i know!!!

Why can't you see chloroplasts under microscope?
Chloroplasts are very small and transparent structures within plant cells, making them difficult to observe under a light microscope without staining. Additionally, they are easily disrupted during the preparation process for microscopy. Special techniques, such as electron microscopy, are often needed to visualize chloroplasts with detail.

Why are electron microscopes more useful than light microscopes for looking at organelles?
Electron microscopes have shorter wavelengths of electrons than light microscopes, allowing for higher resolution images. This enables electron microscopes to visualize smaller structures like organelles with more detail and clarity compared to light microscopes. Additionally, electron microscopes can magnify objects thousands of times, providing a more detailed view of organelles.

You can see chloroplasts and a nucleus under a light microscope.
