An electron in the 2nd excited state is trapped in a 1-d infinite square well with edges at x-o and x 0.9 nm. a. sketch the wavefunction of the electron. b. calculate the energy of the electron. c. what is the probability of finding the electron between 0 and 0.3 nm? d. the energy of the sides of the well is lowered from infinity to about 10 ev. without calculating, describe how the energy and wavelength of the electron will change and explain why these changes will occur based on the wavefunction.
