In this document provided, you will find summaries of various topics in the unit 1 applied science, but this document is physics related only. It started with waves, and how to find the refractive index, it includes step by step practice questions, to fully understand how I got the answer. Then I have summarised snells law, what it is, and how to work it out! Again I provide practice questions I've worked out step by step. After I continue with waves and optical fibre in communications, such as...
