Four equation practice sheets for Snell’s Law (n=sin i / sin r), Refractive Index (n=c/v) and The Critical Angle (n=1/sinC). These are the refraction formulae needed for the Physics component of the new (from 2016) BTEC Applied Science Level 3 - Unit 1.
These were developed for a student who needs plenty of guidance through the maths and is also Visually Impaired. He was working on these at home with his Mum during the coronavirus lockdown. So I have modelled worked examples and given hints, to build confidence. The last sheet involves two-step calculations using these formulae and the equations for velocity (v=s/t) and the wave equation (C=fλ)
I have provided this as an editable free resource as I have benefited from other editable free resources that others have uploaded - many thanks to those contributors.
Hope this is helpful - PLEASE leave feedback ;)

Super resource, many thanks
So, I am studying this course and we some mock exams coming up. I was searching for some practice questions and these are perfect. The recalls of each equation and examples are very simple to understand. Thank you so much for creating this resource. The only thing that I'd like to see is an answer sheet to ensure that my answers are correct. When I practice on past papers and finish on a question, I personally check my answers and working out is correct using the mark scheme.
