Term 2 Reflections

In Term 2, we learnt about Optics under Physics. To me, optics was about drawing, measuring and calculating. Optics requires one to draw the ray diagrams accurately, without leaving anything out. Also, Optics requires one to calculate angles, such as the critical angle. Calculating critical angles requires trigonometry, which at that time we have not learnt yet. Because of that, I was unable to manipulate the numbers and hence could not find out the critical angle in the test, costing me 2 marks. Overall, I still did okay for my test, scoring 73/100. I really wanted to score an A1 for this term, and tried to study really hard, but I just could not get enough marks to score that A1. Optics to me is actually quite simple, once you have mastered the techniques of drawing the ray diagrams.
