You must read each slide, and complete any questions on the slide, in sequence.

This widget displays 3D and contour plots of wavefunctions of a particle in a one-nanometer square box.

Use the WolframAlpha widget to answer the following questions:

1.

With a quantum number of 2 in the x direction, and a quantum number of 2 in the y direction you would expect to see peaks in the contour plot at which of the following coordinates:

x = 0.25, y = 0.25 and x = 0.25, y = 0.75

x = 0.25, y = 0.75 and x = 0.75, y = 0.25

x = 0.25, y = 0.25 and x = 0.75, y = 0.75

x = 0.25, y = 0.25 only

2.

With a quantum number of 5 in the x direction, and a quantum number of 4 in the y direction, how many peaks in the contour plot would you expect to see?

Feedback will go here.
