The microscope should be positioned at least a few inches away from the edge of the table to prevent accidental falls and damage. A distance of about 6 to 12 inches is generally recommended to ensure stability and easy access while working. Additionally, keeping it away from the edge helps maintain a safe and organized workspace.
A microscope should be placed on a stable, flat surface, ideally about eye level, to ensure comfortable viewing. Position it about 12-18 inches from the edge of the table to prevent accidental tipping. Additionally, ensure there is enough space around the microscope for easy access to the controls and slides.
Typically, a pendant light should hang around 30-36 inches above the dining room table. This allows for optimal lighting and prevents the light from being too low or too high. Adjust as needed based on the size of your table and the height of your ceiling.
No ten thousand is too far, given the wavelength of light, the limiting factor for optical microscopes. Perhaps a 1200 magnification is the practical limit for a simple light microscope.
To see a centriole, you need an electron microscope, specifically a transmission electron microscope (TEM) or a scanning electron microscope (SEM). These microscopes provide the high resolution necessary to visualize the small structures within a cell, as centrioles are typically around 200 nanometers in diameter, far smaller than what light microscopes can resolve.
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
A microscope should be placed on a stable, flat surface, ideally about eye level, to ensure comfortable viewing. Position it about 12-18 inches from the edge of the table to prevent accidental tipping. Additionally, ensure there is enough space around the microscope for easy access to the controls and slides.
Table legs should be placed approximately 1-2 inches from the edge of a table for stability and support.
At least 10 centimeters. Preferrably keep it near the center, so its very hard to fall.
apple=round, round=roll, roll=far as possible, far as possible=edge of table, edge of table=drop off point....
The dinner plate should typically be placed about one inch from the edge of the table. This distance ensures that the plate is easily reachable for diners while maintaining a neat appearance. Additionally, it allows enough space for utensils and glassware to be arranged properly without crowding the plate.
at least 2"
In measuring a table, "depth" refers to the distance from the front edge to the back edge, essentially indicating how far back the table extends. It is an important dimension for determining how much usable space is available for placing items on the surface. Depth is typically measured perpendicular to the table's width and height.
The dining table should be at least 5 feet away from the grill.
For optimal stability and balance, the table legs should be positioned about one-quarter of the length of the table from each end.
There is no spot for the black ball on a pool table.
Table legs should be placed approximately one-fourth of the total length of the table in from the edges for optimal stability and balance.
