1. ¿Qué enunciado está respaldado por la información que se presenta?
A. La longitud de onda de una onda transversal se puede medir
B. Cuanto más grandes son las crestas y las depresiones de una onda
transversal, más se alejan las partículas de su posición de reposo.
únicamente de cresta a cresta.
C. Las ondas transversales hacen que las partículas se muevan en
la misma dirección que la onda.
D. La longitud de onda de una onda transversal mide cuánto se alejan
las partículas de su posición de reposo.

Consider the particle-in-a-box problem in 1d. a particle with mass m is confined to move freely between two hard walls situated at x = 0 and x = l. the potential energy function is given as (a) describe the boundary conditions that must be satisfied by the wavefunctions ψ(x) (such as energy eigenfunctions). (b) solve the schr¨odinger’s equation and by using the boundary conditions of part (a) find all energy eigenfunctions, ψn(x), and the corresponding energies, en. (c) what are the allowed values of the quantum number n above? how did you decide on that? (d) what is the de broglie wavelength for the ground state? (e) sketch a plot of the lowest 3 levels’ wavefunctions (ψn(x) vs x). don’t forget to mark the positions of the walls on the graphs. (f) in a transition between the energy levels above, which transition produces the longest wavelength λ for the emitted photon? what is the corresponding wavele
