An electron is accelerated from rest through a potential difference.After acceleration the electron has a wavelength of 880 nm.What is the potential difference responsible for the acceleration of the electron? A)1.9 × 10^-6 V B)1.7 × 10^-6 V C)2.2 × 10^-6 V D)2.5 × 10^-6 V

Question

Quizplus · Accepted Answer

The de Broglie wavelength formula λ = h/p can be used, where p = √(2meV). Solving for V using λ = 880 nm gives V ≈ 1.9 × 10^-6 V.
