A student investigates the refraction of a narrow beam of monochromatic light as it travels from air into a concentrated sugar solution. They measure the angle of incidence, θi\theta_iθi, and the angle of refraction, θr\theta_rθr, for several different trials.
Their plotted results and line of best fit are shown on the graph below:
Explain how the graph shows that the angle of refraction inside the solution, θr\theta_rθr, is not directly proportional to the angle of incidence, θi\theta_iθi.
Electromagnetic waves Questions
Practise AQA GCSE Physics Electromagnetic waves with exam-style questions for Foundation and Higher tier. 52 questions covering Types of electromagnetic waves, Properties of electromagnetic waves 1, Properties of electromagnetic waves 2, Uses and applications of electromagnetic waves, Lenses (physics only), and Visible light (physics only), matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
