Light microscopes can be illuminated with either natural or artificial light. Artificial light is often the best because it be put directly on the object magnified.
degree of magnification for a light microscope
Yes, the electron microscope is capable of more than 100,000 times magnification compared to only a few thousand times for a regular light-illuminated optical microscope.
The moon is illuminated by the sun. It is not luminous, since it emits no light of its own, only reflected light.
It depends on why the light is illuminated. The only way to find out is with a scan tool.
If only half your viewing field is lit, twist objective lenses until they click into place.
An electronic microscope's strength depends on if it's a light microscope or an electron microscope. A light microscope can only perform a few thousand times magnification but an electron microscope can go into many hundreds of thousands of times magnification.
A light microscope is an optical microscope. That differentiates it from an electron microscope, a quantum mechanical tunneling microscope and others.
Eukaryotic flagella are visible through a light microscope. Bacterial flagella are only visible with a light microscope if they are specially stained with a mordant and a flagella stain.
A burned out bulb, a blocked eye piece, a dislodged mirror or your other eye is closed.
They are not bright enough to be seen when the atmosphere is illuminated by scattered sunlight, which makes the sky look blue, during the day.
A blue filter only allows shorter wavelengths of light to pass. So, covering the light source of a light microscope with a blue filter shortens the wavelength of light passing through the objective.
