Why does an electron microscope have a much higher resolution than a light microscope?
Why does an electron microscope have a much higher resolution than a light microscope?
- Due to its higher numerical aperture
- Due to its lower magnification capabilities
- Because it uses shorter wavelengths (correct)
- Because of the large refraction in air
