Learning application of each physics concept, principles or law is vital in order for u to do well in paper 2 section A,B &C. U should attempt at least 1 section B/C question every day..if u couldn afford to do it, at least do plenty of questions on sect A,B & C every week.
Some might asked ..what is actually a physics concept??
Pressure, impulsive force, momentum, total internal reflection are examples of physics concept that we learned in form4. Basically in SPM, for each concept u had learned, u must at least be able to describe its application.
For example..lets recall about total internal reflection..
In order for total internal reflection to occur, there are conditions need to be obeyed:
1. Light must travel from an optically dense medium to a less dense medium ( e.g from glass to air)
2. incident angle (i) > critical angle (c)
Once u fully understood the whole concepts..its time to know where u should apply it. For this one, we can apply it in fibre optics. Thus its a must for u to describe how fibre optics work based on total internal reflection concept. This video lecture might help u to understand it better..
If u wanna know more detail about fibre optics, u should watch this!
