OGS.12.PS5.1Open Global Science Standards 2026™ · 11th GradeModel wave-particle duality and quantum phenomena: analyze blackbody thermal radiation, the photoelectric effect (E = hf = Phi + KEmax), cut-off frequency, photon momentum, de Broglie matter wavelength (lambda = h/p), electron diffraction, X-ray bremsstrahlung emission limit, and the Heisenberg uncertainty principle.
OGS.12.PS5.2Open Global Science Standards 2026™ · 11th GradeInvestigate atomic electron energy levels and spectra: calculate photon emission and absorption frequencies during quantum state transitions (E = hf = E2 - E1) using the Rydberg formula for hydrogen, and explain the origins of continuous, emission line, and absorption spectra in laboratory and astronomical contexts.
