Placing a microscope with its arm facing you allows for easy access to adjust the focus dial and change slides conveniently without having to reach around the microscope. This setup ensures smooth and efficient use of the microscope during observation and analysis.
You should adjust the distance between the objective lens and the specimen. Try increasing the distance slightly to avoid seeing your eyelashes. Additionally, check that your eyes are properly aligned with the eyepiece to prevent any obstruction in the field of view.
Short answer: Zacharias Jansen Long answer: Your question is not valid for 2 reasons: 1. You cannot "discover" something if it does not exist. You should be asking who invented it, not who found it laying around somewhere. 2. A "simple microscope" is not common terminology. Simple compared to an electron microscope? or simple compared to a compound microscope? What is typically referred to as just "microscope" is technically a compound microscope. A set of multiple lenses mounted in a desktop style that allows the compounding of magnification. A compound microscope is the standard microscope in any basic lab setting. Anything more "simple" than a compound microscope would not even really be a microscope, it would either be a telescope, or simpler than that is a magnifying glass (with a single lens) The inventor of the magnifying glass was: Roger Bacon The next step up is the telescope invented by: Zacharias Jansen The next step up is the "compound microscope" which was also invented by: Zacharias Jansen (this is the simplest form of what would be recognized as or named "microscope") If you wanted to go even "simpler" and define microscope as anything that magnifies, there were reading glasses around for thousands of years prior, and even "reading stones" which were lumps of polished glass used to magnify parchment in Egypt as far back as 7000 B.C. (inventor unknown). So it really depends on how you wish to refine your meaning of simple. The magnification of anything? There is no known inventor for reading stones, his name is lost to time. Or if you mean the first invented microscope that could examine things too small for a human eye to detect, that's a compound microscope. Thus if I am guessing your meaning correctly, you meant to ask this question: Question: Who invented the compound microscope? Answer: Zacharias Jansen
None. A microscope is not need to figure out the mintmark. It is big enough to see. You can however use a magnifying glass to see other details better.
The student should adjust the condenser to allow more light to pass through the specimen in a compound light microscope. By adjusting the condenser height or iris diaphragm, the amount of light reaching the specimen can be controlled for better visibility.
To allow more light to pass through a specimen in a compound light microscope, one should adjust the condenser. By adjusting the condenser's aperture, one can control the amount of light that reaches the specimen, affecting the brightness and clarity of the image.

you should make sure the microscope is clean and ready. and that it is set on the right setting. i actually have no clue . suckerrr
Starting with the stage and lens close together in a microscope allows for easier focusing of the specimen. By beginning with the the stage close to the lens, you can quickly bring the specimen into view without having to adjust the focus knob too much. This helps in quickly locating the specimen and then making fine adjustments for a clearer image.
A scanning electron microscope (SEM) will be ideal to observe the pores of human skin. A compound light microscope will suffice to view the sex of a fruit fly. A compound light microscope can also be used to observe the spores of a fern.
A compound light microscope is typically used to observe amoebas due to their small size. This type of microscope allows for higher magnification and resolution, making it easier to study the intricate details of amoebas.
You should have payed attention in class what hehe
you should study more so that you'll know the answer
To observe a skin cell at the highest magnification through a microscope, you should first place the skin cell slide on the microscope stage, focus the microscope using the coarse and fine focus knobs, adjust the light intensity, and then increase the magnification to the highest level possible on the microscope objective.
A microscope should be held with two hands, one on each side of the base to ensure proper stability and balance. Keep your fingers away from the lenses and focus knobs to avoid damaging the delicate components. Adjust the position of the microscope on the table to ensure a comfortable viewing angle.
You should adjust the stage controls to move the slide left, right, up, or down to center the image in your field of view.
