Today, we went through our online worksheets 4 and 5. It is about refraction of light and the application of refraction of light, like periscope etc. Our teacher started on refraction as the test topics were already covered, and thus we proceed on to refraction, before lenses next week.
Today, we basically just recap what we have learnt about refraction last lab lesson. I find this lesson useful, even though we have learnt about refraction last lab lesson. This is because the lab lesson mostly tested our accuracy when doing the experiment. However, today we get to apply what we have learnt into application questions and even drawing the rays. The worksheets have shown us really good examples of how question may ask us about refraction. However, as practice makes perfect, it would definitely be better if we could seek for more questions, and the more we practise, the better we are at application questions. At the end of the class, I'm glad that the teacher gave us 1 more worksheet on reflection so as to prepare us for the test !
