Dual Nature of Radiation and Matter — Class 12 CBSE Physics revision notes
A 3-page visual revision sheet for Dual Nature of Radiation and Matter, written for Class 12 CBSE 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.
What this Dual Nature of Radiation and Matter sheet covers
- Photon energy
- Work function
- Max kinetic energy
- The photoelectric effect, observed
- Einstein's photoelectric equation
- energy balance
- work function from threshold frequency
- stopping potential
- What raises current vs what raises stopping potential
- Raise the intensity
- Raise the frequency
- The two experimental graphs
- photocurrent at a large collector voltage, fixed frequency and intensity
- photocurrent past saturation voltage, fixed frequency
- Particle nature of light: the photon
- de Broglie waves
- de Broglie wavelength, any particle of momentum p
- after acceleration through potential V, charge q
- for an electron specifically
- Wave-particle duality, both directions
- Symbols
- Traps that cost marks
- Tricks that save time
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 Dual Nature of Radiation and Matter 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.
