Description of the activity/assignment

This problem set is designed to test students' understanding of x-rays. Students are given wavelengths and asked to calculate minimum potential energy, radiation frequency, and whether or not the mineral can be used as a radiation filter. They are also asked to determine the 2-theta for different crystal face x-ray diffractions given cell edge length and radiation wavelength.

Determining whether students have met the goals

Students have successfully met the goals of the assignment if they answer the problem set thoroughly and accurately.
