Question

This question and the following two refer to the same situation An electron is moving in the potential U(x) shown to the right. This potential is an even function of x. The energies, E_1 = -1.5 eV and E_2 = +0.5 eV, of the two lowest energy states are indicated by the dashed lines. Five x values are labeled A-F in the figure. Psi_1(x) is the wave function of the ground state, and psi_2(x) is the wave function of the first excited state. Which one of the following statements is not true? Psi_1(A) = psi_1(F) psi_2(A) = -psi_2(F) Both psi_1 and psi_2 are proportional to sin(kx) in the regions A

Explanation / Answer

C option

both a and b option is corect

in D option dphi/dx = 0 slope = 0

for x < A doube diferentiation is positive means minima

so <A is minima
