Easter revision sessions!

Last year I ran very successful revision sessions for A-Level and GCSE/IGCSE Level Physics, so I am doing the same this year. If you want to participate, you can find details and sign up following the links below: For GCSE/IGCSE Level: https://physicswithkeith.com/gcseeaster2024/ For A-Level: https://physicswithkeith.com/aleveleaster2024/ The sessions are interactive, and cover important exam technique andContinueContinue reading “Easter revision sessions!”

Deriving the speed of light from Maxwell’s Equations

I thought it’d be good to show my A-Level students how to model an electromagnetic wave using a sinusoidal wave function for the electric and magnetic fields, and how these can be substituted into Maxwell’s Equations to derive the speed of light. There are a few ways to derive the speed of light from Maxwell’sContinueContinue reading “Deriving the speed of light from Maxwell’s Equations”
