Explain the difference between a light scanning and electron microscope?
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.
What is the difference between a light microscope and a TEM?
A light microscope uses visible light to magnify samples for observation, while a TEM (transmission electron microscope) uses a beam of electrons to image specimens at a much higher resolution. TEM can visualize structures at the nanometer scale and provide detailed internal information due to its high magnification capabilities.
Is there any difference between compound microscope and inverted microscope?
Special type of compound microscope, developed c. 1850, in which the specimen is illuminated from above and observed from below. A prism placed under the specimen reflects the light rays into body-tube. This feature made it possible to observe reactions without visual disturbance from the gases or the effervescence generated by them. so highly used in tissue culture experiments
What came first electron microscope or light microscope?
compound light microscope - cell theory - electron microscope
Is bacteria too small to be seen with an ordinary light microscope?
Yes, most bacteria are too small to be seen with an ordinary light microscope. Bacteria are generally between 0.5 to 5 micrometers in size, which is below the resolution limit of a light microscope which is about 200 nanometers.
What is the difference between a optical microscope and a non- optical microscope?
light is must for optical microscope while is not necessary for nonn optical one
What is the difference between a compound microscope and a light microscopes?
light microscopes shoe only black and white pictures. When a compound microscope shows color when you look through the eye-piece.
What is the thing called that provides light for a microscope?
Light source, can be mirror or electric light.
What is the difference of a light microscope and a scanning electron microscope?
A light microscope uses visible light to magnify and view specimens, offering lower magnification and resolution compared to a scanning electron microscope (SEM) which uses a focused beam of electrons to image the sample, providing higher magnification and resolution. SEM can produce 3D images of the sample surface while light microscopes typically provide 2D images.
What is the major difference between the light microscope and the electron microscope?
Electron microscopes can see much closer than a light microscope, and they use electrons to paint a picture of what the object looks like. Giving a very detailed and small picture that can be viewed on a monitor.
What is the difference between microscope today and a long ago?
If you are talking about a light microscope, not very much. The largest difference is varying lenses and the light source. Today the light is uniform from a bulb and not from a candle or the sun. Also modern ones are more powerful because of the precision used to make them
What is the difference between s and p polarized light?
S and p polarized light refer to the orientation of the electric field in a light wave. S polarized light has the electric field perpendicular to the surface it is reflecting off of, while p polarized light has the electric field parallel to the surface. This difference affects how the light interacts with surfaces and materials.
What is the difference between ordinary microscope and electron microscope?
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.

What is the difference between p and s polarization in the context of light propagation?
In the context of light propagation, the difference between p and s polarization lies in the orientation of the electric field. P polarization has the electric field oscillating parallel to the plane of incidence, while s polarization has the electric field oscillating perpendicular to the plane of incidence. These orientations affect how light interacts with surfaces and materials.
What is unpolarized light and how does it differ from polarized light?
Unpolarized light is light in which the electric field oscillates in all directions perpendicular to the direction of propagation. Polarized light, on the other hand, is light in which the electric field oscillates in a specific direction. The main difference between unpolarized and polarized light is the orientation of the electric field vibrations.
What is the difference between s polarized and p polarized light?
S polarized light has its electric field oscillating perpendicular to the plane of incidence, while p polarized light has its electric field oscillating parallel to the plane of incidence.
