複選題40. Which of the following statements about "The Bohr Model" and "Particle in a Box" areTRUE?(A) A function of the type A cos(Lx) can be an appropriate solution for the particle in a one-dimensional box.(B) If the wavelength of light necessary to promote an electron from the ground state to thefirst excited state is λ in a one-dimensional box, then the wavelength of light necessary topromote an electron from the first excited state to the third excited state will be λ/2.(C) The total probability of finding a particle in a one-dimensional box (length is L) in energylevel n = 4 between x = L/4 and x = L/2 is 25%.(D) For an electron trapped in a one-dimensional box, as the length of the box increases, thespacing between energy levels will increase.(E) Assume that a hydrogen atom's electron has been excited to the n = 5 level. When thisexcited atom loses energy, 10 different wavelengths of light can be emitted.
