What microscopes do you know? Describe the principle of their action.

Light – A beam of light rays falling into a microscope is first converted to a parallel stream, and then refracted in the eyepiece. Then the information about the object of study enters the human visual analyzer.
Electronic Transmissive – In a transmission electron microscope, electrons pass through an object that must be thin enough for this study.
Electronic Scanning – The sample under study in an industrial vacuum environment is scanned by a focused electron beam of medium energy.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
