Refraction of Light at Plane Surfaces — Class 10 ICSE Physics revision notes
A 4-page visual revision sheet for Refraction of Light at Plane Surfaces, written for Class 10 ICSE Physics. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.

How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Physics chapter by chapter against your real exam dates and free hours, and when the plan reaches Refraction of Light at Plane Surfaces the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
