Wave/Particle Dualityde Broglie - Multiple Choice QuestionsQ1. Electrons and protons in two beams are travelling at the same speed. The beams are diffracted by objects of the same size. Which correctly compares the de Broglie wavelength λe of the electrons with the de Broglie wavelength λp of the protons and the width of the diffraction patterns that are produced by these beams?
Q2. A proton moving with a speed 𝑣 has a de Broglie wavelength λ. What is the de Broglie wavelength of an alpha particle moving at the same speed 𝑣?
