A student is given a rectangular glass block, a ray box with a narrow slit, a sheet of plain paper, a pencil, a ruler and a protractor.
Describe how the student could use this equipment to investigate how the angle of refraction depends on the angle of incidence when light enters the glass block.
84 exam-style questions on Edexcel GCSE Physics 5.2 The electromagnetic spectrum, covering 5.2.1 Electromagnetic waves and refraction in glass (core practical), 5.2.2 Groups of the electromagnetic spectrum, 5.2.3 Wavelength-dependent behaviour of EM waves, and 5.2.4 Velocities of EM waves in different substances. Each one has a worked solution and a mark scheme showing where the marks go.
