Why does an electron microscope have a significantly higher resolution than a light microscope?
Show answer and explanation
Correct answer: The wavelength of an electron beam is much shorter than visible light
The resolution of any microscope is limited by wavelength. Since high-velocity electrons have wavelengths thousands of times shorter than visible light photons, they can resolve structures at the atomic and molecular level.
