GENERAL HISTOLOGY

Detailed explanation-1: -In contrast to light microscopes, electron microscopes use a beam of electrons instead of a beam of light. Not only does this allow for higher magnification and, thus, more detail, it also provides higher resolving power.

Detailed explanation-2: -Turn the coarse focus knob slowly until you are able to see the cells. Turn the fine focus knob slowly until the cells are in focus and you can see them clearly. Repeat steps 1-5 using the higher power magnification to see the cells in more detail.

Detailed explanation-3: -Most cells are so small that they cannot be viewed with the naked eye. Therefore, scientists must use microscopes to study cells. Electron microscopes provide higher magnification, higher resolution, and more detail than light microscopes.

Detailed explanation-4: -The high-powered objective lens (also called “high dry” lens) is ideal for observing fine details within a specimen sample. The total magnification of a high-power objective lens combined with a 10x eyepiece is equal to 400x magnification, giving you a very detailed picture of the specimen in your slide.

Detailed explanation-5: -If we try to magnify further, we won’t be able to see any more detail than this – just like the digital photo above, the microscope will have reached the limit of its resolution. Different types of microscope have different resolving powers. Light microscopes let us distinguish objects as small as a bacterium.
