This resource contains many past papers and mark schemes for Unit 2 of the Edexcel Physics A-Level.
This module involves the study of waves (including refraction, polarisation, diffraction and standing (stationary) waves), electricity (current and resistance, Ohm’s law and nonohmic materials, potential dividers, emf and internal resistance of cells, and negative temperature coefficient thermistors) and the wave/particle nature of light.
These documents are freely available on the Edexcel website.
