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.
4,322 Questions
Does a compound microscope only have 1 lens?
No. If it only has one lens, then it's just a magnifying glass, not a microscope.
Which focus knob should you use first when looking at a specimen?
You MUST use the coarse focus knob.
What is the name of the part which holds the slide in place on a microscope?
The part that holds the slide in place on a microscope is called the stage. The stage is where you place your sample slide for viewing under the lens of the microscope.
Which microscopes creates an image of the surface of a sample?
A scanning electron microscope (SEM) creates images of the surface of a sample by scanning the surface with a focused electron beam and detecting the emitted secondary electrons. This results in detailed 3D topographical images with high resolution.
The movement of a living organism in a wet mount slide into and out of focus within the field of view is due to the organism shifting its position vertically in the water droplet. As it moves up and down, it comes into and goes out of focus at different depths of the water droplet. Adjusting the fine focus knob on the microscope helps bring the organism back into focus as it moves.
What is the cover over the specimen called on microscope?
The cover over the specimen on a microscope is called a microscope slide cover slip. It protects the specimen from dust and damage and helps to maintain the specimen in place while observing it under the microscope.
Most slides have to be either wet or stained in order to be properly viewed under a microscope. This includes potatoes, where if you want to see the starch, you will have to wet the slide and add stain.
What microscopes can enlarge images up to 100000 times or more?
An electron microscope can enlarge images up to 10,000,000 times (107x).
Other types of microscopes that can achieve over 105 magnification include scanning probe microscopes, such as atomic force microscopes, electrostatic force microscopes, magnetic force microscopes, scanning tunneling microscopes, and piezo force microscopes.
Should you leave oil on a 100x objective lens when you put the microscope away?
No, it is best to clean the oil from the 100x objective lens using lens paper or a clean cloth specifically made for cleaning lenses before putting the microscope away. Leaving oil on the lens can attract dust and debris, leading to a blurry image and potentially damaging the lens.
What is a condenser lens used for?
A Condenser Lens is a device made up of a series of lenses and sometimes a mirror, that is used to gather and 'focus' light to direct it onto an object through a different projection lens.
Why should you always start with low power when using a microscope?
You don't have to its just to see the different cycles.
What type of microscope did Leonardo da vinci use?
Considering the microscope wasn't invented until 100 years or so after his death, he didn't use any kind at all.
Are there limitations of a microscope?
there will always be limitations to a microscope, but we will always be able to make an improved one which can see further than the one before...
What microscope use a beam of electrons instead of light?
An electron microscope uses a beam of electrons instead of light to magnify specimens. This allows for higher resolution images and the ability to view smaller details compared to light microscopes.
How does microscopes help scientists observe objects?
Microscopes help scientists observe objects by using lenses to magnify their size, making small details visible. They allow scientists to view objects at a level of detail that is not possible with the naked eye, enabling them to study the structure, composition, and properties of the object being observed.
How does the lens of a light microscope make things look larger?
Look at your hand - 'end-on' and you see five finger-tips. The effect of the magnifying lens is to 'discard' the fingers to the left and right, and enlarge the image that remains in the center of the field of view.
What type of microscope uses a magnetic field magnifies up to one million times?
A scanning electron microscope (SEM) uses a magnetic field to focus a beam of electrons onto a specimen. This microscope can magnify samples up to a million times and provides detailed information about the surface topography and composition of the specimen.
