Wave function of infinite square well but with time dependence included

In summary, the wave function of an infinite square well with time dependence included is a mathematical representation of the probability amplitude of a particle confined within an infinitely deep potential well. Time dependence introduces a time factor into the wave function, causing it to oscillate and change over time. The boundary conditions for the wave function require it to be continuous and differentiable within the well. The energy of the particle affects the frequency and wavelength of the wave function, with higher energies resulting in shorter wavelengths. Additionally, the wave function can be used to determine the probability of the particle being in a specific energy state through the probability density.

Homework Statement


Find the wavefunction for an infinite well, walls are at x=0 and x=L(include the time dependence)




The Attempt at a Solution


I don't understand what it's meant by include the time dependence. Can I just find the time-independent wavefunction and then multiply it by [tex]e^{-iwt}[/tex] ? Or do I have to start from the Schrodinger equation?

Related to Wave function of infinite square well but with time dependence included

1. What is the wave function of an infinite square well with time dependence included?

The wave function of an infinite square well with time dependence included is a mathematical representation of the probability amplitude of a particle confined within an infinitely deep potential well. It takes into account the time evolution of the system and is described by the time-dependent Schrödinger equation.

2. How does time dependence affect the wave function of an infinite square well?

Time dependence introduces a time factor into the wave function, which causes it to oscillate between positive and negative values. This time factor is known as the phase factor and is given by e^(-iEt/ħ), where E is the energy of the particle and t is time. This means that the wave function will change over time and the particle's probability of being found in a certain position will also change.

3. What are the boundary conditions for the wave function of an infinite square well with time dependence included?

The boundary conditions for the wave function of an infinite square well with time dependence included are that the wave function must be continuous and differentiable everywhere within the well. This means that the wave function must have the same value at the boundaries of the well and cannot have any sudden changes or discontinuities.

4. How does the energy of the particle affect the wave function of an infinite square well with time dependence included?

The energy of the particle is directly related to the frequency of the oscillations in the wave function. As the energy increases, the frequency of the oscillations also increases, resulting in a shorter wavelength for the wave function. This means that the particle has a higher probability of being found in the center of the well, where the wavelength is the shortest.

5. Can the wave function of an infinite square well with time dependence included be used to determine the probability of the particle being in a specific energy state?

Yes, the wave function of an infinite square well with time dependence included can be used to determine the probability of the particle being in a specific energy state. The probability is given by the square of the amplitude of the wave function at that energy state, which is known as the probability density. This allows us to calculate the probability of the particle being in any energy state within the well at any given time.
