Try this first
In the context of electron microscopy, what does a shorter de Broglie wavelength imply about the electrons used?.
- A.They have lower energy.
- B.They have higher energy.
- C.They travel slower.
- D.They are less focused.
Model answer
What a good answer should say
- They have higher energy.
Explanation
Why this works
A shorter de Broglie wavelength indicates that the electrons possess higher momentum and energy, which enhances their ability to resolve fine details in the sample being observed.
