Microscopy, optical and electron microscope with ray diagram
The closest distance of separation (i.e. resolution) visible to the human naked eyes is 0.1 mm. Inside details of solids, crystals, unit cells, atoms, electrons, and imperfection demand for visibility of much smaller dimensions. The smaller dimensions may be as small as 1 Angstrom(10 -10 m) or less. These situations need a magnified vision. This is possible through a microscope. Microscopes of various magnification ratio are used according to the need. Their magnification generally varies between 5 to 1000000. Microscopes are broadly classified into following main categories. 1. Optical microscope 2. Electron microscope 3. Field ion microscope 4. Scanning tunneling microscope Here we have listed some magnification and applications of different types of microscopes Type Range of magnification Used in study of Optical microscope 10 to 2000 times linear Microstructure Electron microstructure 100000 times linear...
Difference between Its and It’s and their correct uses
Do you always confuse between “its” and “it’s”? And you might have been using these words incorrectly. Confusion is created with the use of apostrophe. So brush up on the difference between “its” and “it’s”. Here the difference is explained with some examples, practice them and clear confusion. Its Its is a possessive pronoun that is gender neutral.

I love India for its incredible culture. I never experienced its beauty. Sparrow prepares its nest beautifully. My neighbor’s dog never stays in its own yard. Facebook needs to improve its quality to compete with other social websites. It’s It’s is contraction or short for “it is” or “it has”. Its cannot be used for anything else. Examples: It’s (it is) a hot sunny day. It’s...
