    Question: Who discovered 'Electron microscope'?

    Options:

    Robert Hooke
    Zernicke
    Knoll and Ruska
    Aristotle

    🔑Key Points:
    -The electron microscope was co-invented by Max Knoll and Ernst Ruska in the early 1930s.
    -Unlike optical microscopes, electron microscopes use a beam of electrons to create an image of the specimen.
    -Electron microscopes have much higher resolving power than light microscopes, enabling much finer detail to be observed.
    -The discovery allowed for visualization of structures at the nanometer scale, greatly advancing fields like biology and materials science.

     🔴Additional Information:
    -Robert Hooke: An early scientist known for his work with microscopes and the discovery of cells.
    -Zernicke: Frits Zernike was a physicist who invented the phase contrast microscope.
    -Aristotle: Ancient Greek philosopher and polymath.
