I'm doing the physics Concours Général in physics on Thursday, and in math on Monday. To prepare, I looked at previous years' sujet's (I can't find the translation right now), and some talk of a pulsation, omega, in relation to light, that I don't know anything about.
I asked my teacher today and he couldn't come up with a definite answer.
So do any of you know what pulsation is or represents, and what formulas are associated with it?
Thanks for any constructive answers.
