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.
Examples Include:
*Harmonics
*Overtones
*Rays
*Trains, pulse, and continuous waves
*superconductivity
*Doped semiconductors
*Stopping Potential of photoelectric effect
*Continuous emission spectra
*Laser light
*Energy Transitions

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.

Thanks.

Anyone know if we need to learn this?

hope not, i havent, but none of the past papers ive seen have them in it either except perhaps stopping potential and harmonics, which i did in class. the others i have no idea
