difference between light microscopes and electron microscopes

by suitably arranging 'V' (say 300 volts) the wavelength of the electron can be made to As the resolving power of a microscope is inversely proportional to the wavelength of light, the smaller the wavelength, the larger the resolving power. Hence, the resolving power o..

It is a sophisticated form of microscope, which can provide a higher magnification of the object (up to 1,00,000 times or more). The electron microscope employs an electron beam emanating from a cathode, instead of light as in the compound micr..

It is used for the study of internal ultra structure of the cell organelles. It has a resolving power of 2 to 10 0 A. fig. 3.4 - Transmission Electron Microscope..

Small drops of oil formed by a sprayer are allowed to fall in between a positively charged upper metal plate and a negatively charged lower metal plate. The space between the two plates is irradiated with X-rays. This displaces some electrons of the air molecules, which consequently get ..
