Exam-style question
Try this first
Describe the relationship between the de Broglie wavelength and the momentum of an electron.
Model answer
What a good answer should say
- The de Broglie wavelength (λ) of an electron is inversely proportional to its momentum (p), described by the equation λ = h/p, where h is Planck's constant.
- This means that as the momentum of the electron increases, its wavelength decreases.
Explanation
Why this works
This answer clearly outlines the mathematical relationship between de Broglie wavelength and momentum, reinforcing the concept of wave-particle duality. It tests the student's ability to recall and explain fundamental physics principles.
