Indicate true (T) and false (F) statements below regarding electron microscopy. Your answer would be a four-letter string composed of letters T and F only, e.g. FFFF.
( ) Depending on acceleration voltage, the resolution limit of an electron microscope can be as small as 0.05 nm.
( ) The emission gun and the magnetic coils in an electron microscope are analogous to the light source and the glass lenses in a light microscope, respectively.
( ) Contrast in specimens for electron microscopy can be achieved using electron-dense material.
( ) For biological samples, the effective resolution of electron microscopy is about 1 nm.
