Summary Introduction
Introduction:
Various types of lights have been used in several classes of microscopes to examine specimens. The light microscopy is classified into four types based on the application of light on the image to get its appropriate view.
In transmission electron microscopy, a beam of electrons is generated to produce the image on a fluorescent background. It is used to study the internal details of a specimen.
The light microscopy and the transmission electron microscopy differ from each other on the basis of their magnification power, resolution, and wavelength.

Both (b) and (c) are correct. e. All are correct.arrow_forwardIn light microscopy, when magnification is increased, the lens focuses closer to the sample. This makes the user more likely to ram the sample into the lens. Why is it common for the lens to focus closer to the sample at higher magnifications?
