4. This problem concerns superposition. Suppose the wavefunction of an electron

4. This problem concerns superposition. Suppose the wavefunction of an electron in a linear accelerator is =(cos)eikx+(sin)eikx, where (chi) is a parameter. (a) What is the probability that a single measurement will find that the electron has a linear momentum (i) +k, (ii) k ? Hint: your answers should be functions of . (b) What form would the wavefunction have if it were 90 percent certain that the electron had linear momentum +k ? Hint: this problem allows you to determine the value of
