In 1931
compound light microscope - cell theory - electron microscope
The compound light microscope came first, dating back to the late 16th century. The electron microscope was developed much later in the early 20th century.
scanning electron microscope
There is a compound light microscope, an scannignn electron microscope, and transmission electron microscope.
what is the principal of electron microscope
Stereomicroscope, Compound Microscope, Phase-contrast microscope, electron microscope, Scanning-electron microscope, Transmission electron microscope, Confocal-scanning microscope. THESE ARE JUST SOME. :)
The first electron microscope was developed by a German physicist named Ernst Ruska in 1931, along with his colleague Max Knoll. They were awarded the Nobel Prize in Physics in 1986 for their invention.
The four main types of microscopes are the Light Microscope, Electron Microscope, the Transition electron microscope and Scanning electron microscope.
An Electron Microscope is used to study the contents of a nucleus.
Knoll and Ruska are known for their contributions to the development of the electron microscope. Knoll helped improve the resolution of electron microscopes, while Ruska built the first practical electron microscope, revolutionizing the field of microscopy by allowing scientists to see structures at the cellular and molecular level.

An electron microscope is capable of magnifying objects up to a million times. This type of microscope uses a beam of accelerated electrons to view specimens at a much higher resolution compared to light microscopes.
