When you move the slide to the left while looking through a microscope, the image of the specimen on the slide will appear to move to the right in the field of view. This is because the light passing through the slide and specimen is refracted and magnified by the lenses of the microscope.
Robert Hook coined the term cell, while looking through a simple microscope at cork shavings.
If you move the specimen toward you while looking under the microscope, it will appear to move in the opposite direction, away from you, within the field of view. This is because the image seen through a microscope is inverted.
As I learned the hard way if you are adjusting the body of the scope while looking through the lens it is very easy to exceed the pressure threshold of a plate and crack it, destroying your sample and all your hard work. Move the slide and scope into place then look through the lens for fine adjustments.

Racking downwards with the coarse focusing while looking down the microscope can cause the objective lens to crash into the slide, potentially damaging both the lens and the specimen. It is advisable to always rack the focusing knob upwards to bring the specimen into view slowly and avoid any potential collisions.
Field of view refers to the diameter of the area visible when looking through a microscope. It is determined by the microscope's objective lens and eyepiece combination. A larger field of view allows for more of the specimen to be seen at once, while a smaller field of view provides higher magnification but less visible area.
Robert Brown (1773-1858) was a scottish botanist who is largely remembered for the contributions to botany that he made by using the microscope. In 1827 while looking under a microscope while looking at grains of pollen from Clarkia Puchella he noticed that minute particles ejected from the pollen was executing jittery motions. He observed the same phenomenon in an inorganic sample so he was able to conclude that this motion was not related to life. This motion was named Brownian Motion after Mr. Brown.
The interpupillary adjustment on the eyepieces of a microscope allows you to change the distance between the eyepieces to match the distance between your eyes. This helps create a single, merged image and prevents eyestrain or double vision while looking through the microscope.
Magnification and resolution is in light microscope is about 500x and 0.2micro metres respectively than human eye.In e.microscope magnification is about 200,000x and resolution is 0.0005micro metres. You cannot observe live specimen through electron microscope. Lenses in light microscope are glass while e.microscope use magnetic lenses. E.microscope is relatively very larger than light microscope. You need special knowledge to handle electron microscope. You can observe through naked eye in e.microscope. A beam of electrons is sent through specimen in e.microscope.In light microscope a beam of light is sent. Electron microscope is very complex relative to light microscope.
No, the diaphragm of a microscope is used to control the amount of light that reaches the specimen. It regulates the intensity and quality of the light for better visibility and contrast while viewing through the microscope.
