What is the relationship between de Broglie wavelength and the resolution of an electron microscope?.
- A.Resolution improves with longer wavelengths.
- B.Resolution improves with shorter wavelengths.
- C.Resolution is independent of wavelength.
- D.Resolution decreases with shorter wavelengths.
Model answer
What a good answer should say
- Resolution improves with shorter wavelengths.
Explanation
Why this works
According to de Broglie's hypothesis, shorter wavelengths lead to higher resolution in electron microscopy, as they allow for the observation of smaller details due to reduced diffraction effects.
