Why must you use a thin specimen when viewing with a light microscope?

∙ 11y ago
For a light transmission microscope, a thin sample is needed in order for the light to pass through the sample from the light source on the other side. However, you can use a dissection microscope (another type of light microscope) which illuminates the sample from above, eliminating the need for a thin sample size. As the name suggests, this is normally used in dissections, and is of low magnification.

Why must a specimen be thin in order to be viewed under the microscope?
Because light must pass through it.
How must samples be prepared for observation by an electron microscope?
They must be preserved and dehydrated. Once this is accomplished, put the specimen onto a slide, and then the slide is ready to be viewed under the microscope.
Why must a specimen be thin to be viewed under the microscope and why are they sometimes stained with dyes?
To see them better
What two things must be true before the microscope can be switched to high power to zoom in on a specimen?
its what is in the poo
What is the objective lens used to locate the specimen and the first focus?
When viewing a specimen, you must always use the lower power objective lenses first. Low power lens gives the widest field of view and makes it easier to find the specimen when you look through the microscope. Finding the specimen at high power, without first centering it in the field of view at low power, is nearly impossible.
Why must a specimen be very thin to be viewed under a light microscope?
Light microscope works because light goes *through* your specimen. So if the specimen is too thick, then light won't shine through, and you won't see anything.
Why must the prepared specimen for a monocular microscope be very thin?
The specimen prepared for a monocular microscope must be very thin so light can pass through it easily. The light then goes through a series of lenses that magnifies the specimen to appear bigger
Why is the specimen prepared for a monocular microscope must be very thin?
because the specimen is always thin
Why must a specimen be thin in order to be viewed under the microscope?
Because light must pass through it.
What must be done there is too much light that illuminates the specimen you are observing under the microscope?
Turn down the light.
How thin must a specimen be in order to view it on a microscope slide?
Thin enough for light to pass through it.
What are the disadvantages of an electron microscope?
The speciman you are viewing must be in a vacuum, and be coated with a metal film, therefore the specimen can't be alive and if its a Transmission Microscope- Speciman must be extrememly thin so that the electrons can pass through them. The image is black and white.
What must be done if there is too much light that illuminates the specimen you are observing under the microscope?
tang ina ninyo!!
Why are specimen thin?
because the thinner it is the clearer it is too see inside
Why might a microscopist who specializes in the use of microscopes to examine specimens use a light microscope instead of an electron microscope?
An electron microscope requires that the subject be dead to function. In order to receive a picture, the specimen must be coated in chemicals and put into a vacuum, a process which will kill any living specimen. A light microscope, although not as detailed, will allow the scientist to observe living specimens.
Why must the specimen be centered before switching to high power on a microscope?
I don’t know
