Dual Nature of Radiation and Matter
Your child will accept that light behaves as particles while electrons behave as waves. Dual nature generally contributes about five marks, often a photoelectric-equation plus de Broglie-wavelength question. Learners open with the photoelectric effect above threshold frequency, read Einstein equation separating intensity effects from frequency effects, turn to photon momentum as the particle face of light, and close with matter waves through de Broglie wavelength and the Davisson-Germer electron diffraction confirmation. Three misconceptions arise. Students raise intensity to eject electrons b
