Welcome to Physics 442!

Summer 2021

Quick Links

• Direct link to our class on Max: //max.byu.edu/20214-phscs442/  

Downloads for Homework Problems

• Here's the "n_of_air.txt" file that you need for one HW problem: n_of_air.txt
• Here's the Mathematica code to generate zeroes of the Bessel derivative functions (open, then copy and paste into your own notebook): besselprimezeroes.nb
• Here's the graph paper you need for the "graphical Lorentz transformation" HW problem: graphical_velocity_transformation.pdf

Syllabus

• The syllabus and tentative schedule is available on Max. If you'd like a hardcopy you'll have to print that out yourself..
