What is the difference between microscopes

The image that is viewed is coloured. The image that is viewed is in black and white. It has a magnification power of x to approximately going up to x. It has an enlargement power up to x. A high voltage of electricity is not necessary. A high voltage of minimum 50, volts is necessary. There is no risk of radiation. Risk of radiation is present. It does not have a cooling process enabled in the system. It contains an option for cooling to release the heat through high current.

There is no need for a vacuum. For smooth operation, a vacuum is necessary. The type of electron microscope used for studying the internal structure of cells is. Light microscope. Scanning electron microscope SEM.

Compound microscope. Transmission electron microscope TEM. Answer: d. The magnification power of an optical microscope is. Answer: a. Under an electron microscope, you can magnify an object up to. Electron microscope ha high resolving power i. Thus it can resolve down to 0. It has a useful magnification of x to x. EM has direct magnification as high as ,x and photographic magnification is ,x or more. Mechanism of image formation. In light microscope the image formation depends upon of light absorption in different zones of the objects.

In electron microscope, it is due to electron scattering. Image is seen by eyes through ocular lens. No screen is needed. The image is received on zinc sulphate fluorescent screen or photographic plate. No vacuum is needed. EM operates at high vacuum. Cheap and negligible running cost. Very costly and heavy running costs.

Unlike the SEM, however, the TEM uses a slide preparation to obtain a 2-D view of specimens, so it's more suited for viewing objects with some degree of transparency. A TEM offers a high degree of both magnification and resolution, making it useful in the physical and biological sciences, metallurgy, nanotechnology and forensic analysis.
