4 Schr¨odinger Equation and Classical Wave Equation

Show that the wave function Ψ(x, t) = Ae^(i(kx−ωt)) satisfies both the time-dependent Schr¨odinger equation and the classical wave equation. One of these cases corresponds to massive particles, such as an electron, and one corresponds to massless particles, such as a photon. Which is which? How do you know?

The current through a coil as a function of time is represented by the equation I(t) = Ae−bt sin(ωt), where A = 5.25 A, b = 1.75 ✕ 10−2 s−1, and ω = 375 rad/s. At t = 0.880 s, this changing current induces an emf in a second coil that is close by. If the mutual inductance between the two coils is 4.35 mH, determine the induced emf. (Assume we are using a consistent sign convention for both coils....
