Definitions of terms

What is the meaning of thermal equilibrium?
What is the meaning of electric field?
Electric Current? Electromagnetic field?
Refractive Index? Cathode Ray? Natural Frequency?

Any one will help :smile:
For thermal equilibrium, I define it as; no net transfer of heat energy between two regions, there is no temperature difference between the two regions.

Note: I do OCR physics A, so it could be different for you / your exam board
