AP Physics 2
15.1 Quantum Theory and Wave-Particle Duality
An electron initially at rest is accelerated through an electric potential difference \(\Delta V_0\), giving it a final de Broglie wavelength \(\lambda_0\). A second electron initially at rest is accelerated through an electric potential difference of \(4\Delta V_0\). What is the de Broglie wavelength of the second electron in terms of \(\lambda_0\)?
