Why is specimen smaller than200mm not visible with a light microscope?

Because the smallest wavelength of visible light we can see is around 400 nm. Something 200 nm would need an electron microscope to be seen.

What produces an image of a specimen by passing visible light through it?
Its a Light Microscope! (=
What does the illuminator do on a microscope?
To provide light which makes specimen visible .
What are the light source of the microscope for?
to generate light, so the specimen can be examined (sends light through base, diaphragm, stage specimen, slide, objective lens, nose-piece, body, body tube, and eyepiece)
How does a microscope let you see small objects?
It magnifies the specimen by a certain degree to make it appear larger and let you see more detail which were not visible to the naked eye. It is done with the help of lenses which are aided in microscope
What shapes are visible in the specimen?
The visible shape of something is form.

What is the chemical that sometimes is used to make the specimen visible on a microscope?
An example is methylene blue.
How does iodine affect a slide?
It helps some parts of the specimen to become more visible under the microscope.
Chemical sometimes used to make the specimen visible on a microscope?
Methylene blue is an example.
State how an electron microscope differs from a light microscope?
An electron microscope bombards its target with electrons, while a traditional microscope uses visible light. Electrons can be resolved at considerably higher magnifications that visible light (due to their smaller wavelength).
What does the illuminator do on a microscope?
To provide light which makes specimen visible .
What is Dark field microscope?
A Dark Field microscope is one that has a special condensor (light source) that illuminates the specimen in such a way as to enhance the contrast even if it is unstained. When you look at a specimen in a dark field scope, it looks bright, but it is visible against a black background -- the 'dark field.'
What are the light source of the microscope for?
to generate light, so the specimen can be examined (sends light through base, diaphragm, stage specimen, slide, objective lens, nose-piece, body, body tube, and eyepiece)
What is the smallest particle visible under light microscope?
The smallest particle that can be seen with a light microscope is about 0. 2 microns. If an object is smaller than that, the light's wavelength cannot traverse it causing it to fall out of the visible spectrum.

The visible shape of something is form.
What can be viewed with a light microscope?
Anything that is smaller than the wavelength of light, thatmeans that it is smaller than light and therefore is not visible, at all, to know it exists an electron microscope must be used which captures a reflection of the object a scanning electron microscope uses a computer to make the image
