Reflection
The principal of light is applied to microscopes, not sound.
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.
Look here frenz...actually i mean logically there is no sound applied in a telescope.But there is light applied so far that's why we can see what is happening on the space...we can see any object when there is light we cannot see what is happening in the space using sound.So the principle of light is applied in a telescope...any question can ask me at THIVYASINY SARAVANAN blogspot...

The purpose of a microscope is to magnify and resolve tiny objects or structures that are not visible to the naked eye. The principle of a microscope is based on the interaction of light waves or electrons with the specimen to produce a magnified image for observation and analysis.
it passes light by "total internal reflection"
A light microscope, specifically a compound microscope, is commonly used to view Staphylococcus aureus. This type of microscope uses visible light and multiple lenses to magnify and visualize the bacteria at a cellular level. Staining techniques can also be applied to enhance contrast and aid in identification.
compound light microscope - cell theory - electron microscope
The light microscope use the visible light; the electron microscope use an electrons beam.
Another name for the light microscope is the optical microscope.
