Summary
Light microscopes magnify living cells up to about 1000 times, while electron microscopes reveal fine internal detail.
In depth
Light microscopes use glass lenses and typically resolve down to about 200 nm, enough to see cells and large organelles. Electron microscopes use electron beams with much shorter wavelength, resolving down to below 1 nm; TEM shows internal slices and SEM shows surface 3D detail.
Samples usually need staining for contrast, and electron microscopy requires dead, dehydrated samples in a vacuum.
Key idea: magnification makes an image larger, but resolution decides how much real detail you can see.
