State
A light microscope uses visible light and can image living cells; an electron microscope uses electrons for far higher magnification but kills the specimen.
Show
A lab light microscope resolves detail near 200 nanometers; an electron microscope resolves detail near 50 picometers.
Watch for
A student may credit its sharper images to stronger magnification alone, missing the resolving power that actually reveals the extra detail.
