Metal samples among others can be viewed by a light microscope. The light microscope, also known as an optical microscope, can view microorganisms.
A lubricant such as oil, grease, graphite powder or PTFE can reduce the friction between two surfaces. Or using metal balls to space them and reduce the contact surface area as used in ball bearings.
Tungsten is a metal with a high melting point that is often used in incandescent lamps.
Copper, and to a lesser extent gold, are used in conductors.
Light microscopes can magnify objects up to 1000 times their actial size, and they are often used for dissections. Light in the light microscope allows the viewers to see the specimen that is being magnified.
when are different intensities of light used in compound microscope
Electron scanning microscopes scan metal deposited on surfaces.
its called lens paper
A scanning probe microscope is used for observing, studying and measuring surfaces on a fine scale to the level of atoms and molecules. One can find more information about these on Wikipedia.
The stereo microscope is typically used for lower magnifications of larger specimen. It is usually used to view the surfaces of such things as wood and plastic. You can use it for microsurgery, dissection and also for sorting.
Yes . It depends on the metal and (or) preparation of surface .
Compound
The first metal engraving tools were used in ancient times, around 5,000 years ago. Evidence of metal engraving tools has been found in ancient civilizations such as Mesopotamia and Egypt, where they were used to create intricate and detailed designs on metal surfaces.
Oil is used to lubricate two moving metal surfaces, that would be damaged if there was no oil to prevent friction damaging the two surfaces.
There are both fundamental differences, and relationships between these two gives. Stainless steel is an iron based metal alloy. Teflon is a trademarked synthetic chemical used as a nonstick and lubricating coating, often on metal surfaces.
Zinc is often used as a sacrificial metal on iron.
As viruses cannot be seen with the optical microscope, electron microscopes are used. All the "lenses" in an electron microscope are magnetic fields produced by electromagnets and/or electrostatic fields produced by electrically charged metal plates and/or rings.
No, its a ceramic. (Often used as a coating on metal objects.)
