An particle is confined in a one-dimensional "infinite potential well" of width 2a. < -a v (x) 0 -axa (a) derive an expression for the energy eigenvalues ek of this system. (b) if the above particle is an electron, and the width of the box is 2a 5.29 x 10-11m, what is wavelength of the photon emitted if the electron transitions from its first excited state to its ground state? problem-2 at what locations a inside the box would vou expect to never observe an electron in its first excited state?

Imagine you work as a consultant, and your daily job involves listening to the constructive criticism of others. as part of your job, you must listen to opposing viewpoints to make important decisions. in this activity, you are a consulting dam engineer. you must make a decision about four different dams; should they be repaired, taken down, or left alone? you will listen to contrasting opinions about what should be done with the dams before you make the final decision. as the consulting dam engineer, what do you decide to do with this dam? explain your reasoning. by making your decision, did you support the opinions of the mayor and/or the dam safety official? why or why not?
