Considering only the limitations of diffraction, what is the smallest structure resolvable using a 12 keV electron microscope? A) 3.4 × 10⁻¹⁹ m B) 1.1 × 10⁻¹¹ m C) 1.8 × 10⁻⁴ m D) 10 cm

Question

Quizplus · Accepted Answer

The resolution limit in electron microscopy is determined by the de Broglie wavelength of the electrons, which is inversely proportional to the square root of their energy. For 12 keV electrons, the wavelength is on the order of picometers (10^-12 m), making option B the correct choice.
