Detailed explanation-1: -A microscope is an instrument that can be used to observe small objects, even cells. The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is.

Detailed explanation-2: -A microscope is an instrument that magnifies objects otherwise too small to be seen, producing an image in which the object appears larger. Most photographs of cells are taken using a microscope, and these pictures can also be called micrographs.

Detailed explanation-3: -The microscope uses lenses, similar to those in glasses or a magnifying glass, to make things look bigger – this is called magnification. Magnification describes how much bigger an object is made to look through the microscope. If something has a 100x magnification, it looks 100 times bigger than its actual size.

Detailed explanation-4: -A scanning transmission electron microscope has achieved better than 50 pm resolution in annular dark-field imaging mode and magnifications of up to about 10, 000, 000× whereas most light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000×.

Detailed explanation-5: -This makes electron microscopes more powerful than light microscopes. A light microscope can magnify things up to 2000x, but an electron microscope can magnify between 1 and 50 million times depending on which type you use!
