Due: 20 February 2019 @9:15 am No late homework will be accepted.
1) Consider an electron with a normalized wave function defined as 𝜑(𝑥)=𝑀𝑎𝑎𝑥𝑒𝑎𝑥 for 𝑥 >
0 and 0 for 𝑥 < 0.
a) Show that M = 2.
b) For what value of x does 𝑃(𝑥)=|𝜑(𝑥)|2 is at peak.
c) Calculate < 𝑥 >.
d) What is the probability of finding the particle between 𝑥 = 0 and 𝑥 = 1 𝑎
?
2) In a photoelectric experiment, the threshold wavelength for the ejection of photoelectrons
from zinc is 310 nm. Calculate the work function for zinc. Also, calculate the velocity for the
photoelectrons by light of wavelength 2000 Å other than threshold.

is at peak.

c) Calculate < 𝑥 >.

d) What is the probability of finding the particle between 𝑥 = 0 and 𝑥 = 1 𝑎

  1. In a photoelectric experiment, the threshold wavelength for the ejection of photoelectrons

from zinc is 310 nm. Calculate the work function for zinc. Also, calculate the velocity for the

photoelectrons by light of wavelength 2000 Å other than threshold.
