Scanning electron microscope and to the people who like to play games some of us need to pass a test so please stop playin
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.
The beams of the Sun has reached the Earth's surface.

It is used for looking at parts at a very high magnification. It uses a a beam of electrons to create an image of the item being scanned and can magnify it up to 500,000 times.
A bathroom mirror has a reflective film (usually sputtered silver) applied to its rear surface. Unfortunately rear reflective surface mirrors produce slight double images since a small amount of light reflects off of the front surface of the glass in addition to the light reflected off of the silver on the rear glass surface. A front surface mirror has a reflective film (usually an extremely thin layer of vacuum deposited aluminum) applied to the front surface of the glass. The problem with the above types of mirrors is that salt water is corrosive to metals. Salt water exposure would quickly eat away at the silver or aluminum coatings which create the reflection in the above types of mirrors. So instead periscopes use right angle glass prisms since right angle glass prisms inherently produce an internal reflection, since no metal film is needed in order to create this internal reflection, and since the glass is very resistant to corrosion from salt water.
A detection beam on a microscope is a focused light or electron beam used to capture the signals emitted by a sample under observation. It helps to gather information about the specimen's properties, such as its structure, composition, or fluorescence. Detection beams are crucial in generating images or data in various microscopy techniques, such as optical and electron microscopy.
An E.M = electon microscope
different angles due to the uneven surface, causing diffuse reflection.
In an electron microscope, magnification occurs through the use of electromagnetic lenses that focus and control the electron beam. These lenses work similarly to optical lenses in light microscopes by bending and focusing the electrons to produce a magnified image of the sample. By controlling the electromagnetic fields within the lens, the electron microscope can achieve much higher magnification than a traditional light microscope.
No, a beam of electrons is used by an electron scanning microscope. A light microscope uses light waves either reflected off the surface of the object under study, or passed through the object from beneath. Some people might consider a light wave as a type of electron beam, but for the purposes of microscopy, the ESM is capable of far greater magnification than the LM.
optical microscope
a light microscope uses a lamp underr the microscope and an electron microscope sends a beam of electrons down to act like a magnet to suppl light to the object.
Reflects the Light more!...directs the beam to the front.
A light microscope uses visible light to illuminate a sample and magnify its image, making it suitable for observing living cells and larger biological structures. In contrast, an electron microscope uses a beam of electrons to create a highly detailed image of the sample at a much higher magnification, enabling the visualization of smaller structures such as viruses and proteins.
Scanning electron microscope-An electron microscope that forms a three-dimensional image on a cathode-ray tube by moving a beam of focused electrons across an object and reading both the electrons scattered by the object and the secondary electrons produced by it.
When a beam of light strikes a reflective surface it reflects, angle of incidence = angle of reflection
The Electron Scanning Microscope can magnify an object up to 100,000 times because it make use of beam transmission.
