As is always my problem with physics homework, I am probably thinking to hard about this... however, I am not sure how to express this wave function! This is the question: 24) The time independent wave function of a particle is given in the graph below. The function rises linearly from the origin with slope +k. http://uwoshkosh.elitefitness.us/Mod Phys1.JPG This is a single sawtooth. We covered how to express a continuous square wave, but I don't know how to get this wave function. The two questions accompanying this are to find the probability in a specified range, and to find the expectation value of the particle's kinetic energy. These two I know how to do... it's just the wave function that has me baffled! Thanks for any help!
