Question

At time t = 0 the wave function for a particle in a box is given by the function in the provided image, where ψ₁(x) and ψ₁(x) are the ground-state and first-excited-state wave functions with corresponding energies E₁ and E₂, respectively.

What is ψ(x, t)? What is the probability that a measurement of the energy yields the value E₁? What is <E>?

The equation shown is:

\[ \Psi(x) = \sqrt{\frac{2}{3}} \, \psi_1(x) + \sqrt{\frac{1}{3}} \, \psi_2(x) \]

This equation typically represents a wave function \( \Psi(x) \) in quantum mechanics expressed as a linear combination of other wave functions \( \psi_1(x) \) and \( \psi_2(x) \). The coefficients \( \sqrt{\frac{2}{3}} \) and \( \sqrt{\frac{1}{3}} \) are normalization factors ensuring that the total probability across all states is conserved.
