Microscopes

The simplest answer is that they were created to see things, or details, that are too small for the human eye to see. Early tradesmen used simple lenses to see the intricate lines of engravings, or the clasps and fittings on jewelry. When eyeglass makers began combining pairs of carefully-ground lenses, they discovered the principle of optical magnification that is the basis for the microscope (and the telescope). In the case of the microscope, there were immediate practical applications in biology, anatomy, and miniature mechanical gearing.

Microscopes have helped discover everything that is too small to see with your eyes.

Conventional microscopes like the ones you would use in schools to look at cells with helped us to discover.cells. They also help scientists to see smaller components of larger objects.

Electron microscopes (extraordinarily expensive) were only invented in 1933, but these allowed us to see MUCH smaller things such as atoms and the individual particles that make up atoms.

he didn't, but me invented the first modern microscope

they usees mirros and light to see close up

Hans Janssen and his son Zacharias Janssen, Dutch spectacle-makers, are frequently cited as having invented the first compound microscope in 1590, but there is a good deal of dispute. They may not have. Zacharias Janssen was the one who actually made the claim, and in the middle of the 1600's. A number of historians, however, agree that it is imporbable that 1590 is correct. There is a good deal of evidence that Zacharias Janssen was born somewhere around 1590. A link is provided to the Wikipedia article on the optical microscope where a brief history of the device can be reviewed.

I think you ment What are the powers spelled out in the constituion... I would change the question...

His first discovery with the microscope was of bacteria in French wines that were turning them into vinegar, ruining them. This led to his development of Pasteurization, which saved the French wine industry.

He later went on to make many other discoveries.

a cell membrane controls movement of substances in and out of the cell.

Because, it is too small to see with the naked eye.

Robert Hooke looked at cork cells through his crude microscope. In fact he was the one who coined the term cell, as he said the cork cells reminded him of the cells where monks lived.

Its limitation for higher magnification to observe tiny objects of viruses.

Will proper staining and the right organism the nucleus of a cell can be seen without an electron microscope.

It is irregular-shaped because human skin cells don't have cell wall.

The rectangular glass plate you are referring to is likely a microscope slide. Microscope slides are commonly used in laboratories to hold samples for viewing under a microscope. They provide a flat and transparent surface that allows light to pass through the sample for observation.

compound light microscope - cell theory - electron microscope

If it is being viewed through a microscope - as the classification of the question would indicate - then the image moves to the left.

SI unit is used to measure the thickness of a glass slide is very small.it is measured in mm.

there are several kind of different , we can separate :

1- Methods of analysis

2- properties of Methods of analysis

3-properties of their structure

4-resolution and resoiving power of their

Roughly, the advantage is we are able to separate out components of a cell using devices such as a centrifuge for examination and study, and the disadvantaged is that we have to essentially explode a cell to do it and therefore are not able to view the components in action in living cells.

Bourdon gauge is a type of aneroid pressure gauge consisting of a flattened curved tube attached to a pointer that moves around a dial. As the pressure in the tube increases, the tube tends to straighten and the pointer indicates the applied pressure.

The microscope has helped biologists with their study of living things by opening up observations to the world of things smaller than can be viewed with the naked human eye. The field of study is known as microscopy, or microbiology.

Objects that are smaller than the wavelength of visible light, such as viruses, bacteria, and individual cells, can only be viewed with an electron microscope due to their minuscule size. These microscopes use a beam of electrons to create high-resolution images, revealing details that are not visible with a light microscope.
