Hi I am doing the edexcel 6PH02/01 exam this june.
I looked at the specification and to my surprise some stuff in the book that is spoken in detail and what i learnt in school is not in the spec.
*Trains, pulse, and continuous waves
*Stopping Potential of photoelectric effect
*Continuous emission spectra
Can anyone who is taking this exam or has already taken this exam, tell whether we need to learn them, as I'm worried not to learn them.
