What are the practical limits on the resolution of electron microscopes?.
Model answer
What a good answer should say
- The resolution of electron microscopes is limited by factors such as electron wavelength, lens aberrations, and sample preparation.
- The shorter the de Broglie wavelength of the electrons, the higher the potential resolution, but practical issues like sample damage and electron scattering can affect the achievable resolution.
Explanation
Why this works
This answer is strong because it addresses multiple factors that limit resolution in electron microscopy, demonstrating an understanding of the topic. It tests the student's ability to synthesize information about electron microscopy limitations.
