Who is the inventor of the light microscope?
The light microscope was invented around the 1590s by Zaccharias Janssen and his son Hans. It was later improved in 1609 by Galileo.
The light microscope also called the optical microscope uses visibale light and a system of lenses. The actual inventor is difficult to name although Galileo's microscope was celebrated in 1624 and was the first such device to be given the name "microscope". There are claims that a Dutch spectacle-makers Hans Janssen and his son, Zacharias Janssen, but this was a declaration made by Zacharias Janssen himself during the mid 1600s.
The original inventor is not easy to identify. An early microscope was made in 1590 in Middelburg, Netherlands. Two eyeglass makers are variously given credit: Hans Lippershey and Hans Janssen. Note also that Giovanni Faber coined the name microscope for Galileo Galilei's compound microscope in 1625.
How is light used differently to view an image under a compound light microscope and binocular microscope?
The transmission electron microscope operates on the same principle as the light microscope but uses electrons instead of light. What you can see with a light microscope is limited by the wavelength of light. Transmission electron microscopes use electrons as "light source" and their much lower wavelength makes it possible to get a resolution a thousand times better than with light microscope.
