Quantum mechanics as chemists use it, taught by the spectroscopist Robert Field: the photoelectric effect and Compton scattering, boxes and oscillators, hydrogen and many-electron atoms. Strong on spectroscopy, the experimental face of quantization.

Barton Zwiebach takes on the photoelectric effect in MIT's 8.04 Quantum Physics I (Spring 2016). Expect a university-level blackboard treatment; watch it after the lesson, with Einstein's equation from Part 4 and the stopping-potential graph from Part 5 in mind.
Documentary · Caltech
caltech · David Goodstein
Caltech's classic telecourse episode on how evidence that light can act like a particle led to quantum mechanics. After an opening on Planck and glowing bodies comes its photoelectric segment, with Einstein, electrons in a metal and the work function, and Millikan's lab: an animated second pass over sections 4 and 5, before the episode moves on to de Broglie, Bohr and Heisenberg.
Lecture · MIT
MIT OpenCourseWare · David Kaiser
Physicist and historian David Kaiser's lecture on the 'old quantum theory' of light. His posted notes show the arc: blackbody radiation and Planck's h, Lenard's threshold and Einstein's 1905 'heuristic' light quanta, some fifteen years of skepticism, then Compton scattering. History with the physics left in; the deeper setting for section 4.

Lancaster University
Part 1 of a three-part Lancaster University lab series that, in its own description, uses the photoelectric effect to measure Planck's constant: section 5's measurement on a teaching bench. 'Part 2: The Experiment' (5 min) follows on the same channel.

MIT OpenCourseWare · Allan Adams · 2013
Allan Adams' celebrated course starts from superposition and the experimental facts, builds the wavefunction, operators and the Schrödinger equation, then tours scattering, hydrogen, identical particles and band structure before closing on entanglement and Bell's theorem. Calculus and a little linear algebra are enough to keep up.
Lecture · Royal Institution
The Royal Institution · Sean Carroll · 2020
Sean Carroll tells the story from Planck and Einstein through Bohr, de Broglie and Schrödinger, then argues that the measurement problem is still open and makes his case for the many-worlds interpretation. Notice where the history ends and his interpretation begins.

Khan Academy
A clear, chaptered walk through almost exactly what this session covers: how emission depends on frequency, the threshold, why intensity changes only the number of electrons, why the wave model fails, and how photons of energy hf fix it, ending with the photovoltaic effect behind solar cells. Watch for the moment intensity and frequency part ways; it is the heart of the lesson.

Physics Explained
How the light quantum was really born: not from the photoelectric effect, but from Einstein's 1905 thermodynamic argument about blackbody radiation, running from Wien's law and Boltzmann's entropy to the photoelectric equation and Millikan's confirmation. The perfect bridge between the last chapter and this one.

Institute of Physics
A three-minute classroom demonstration from the Institute of Physics and the National STEM Learning Centre: a zinc plate on a gold-leaf electroscope, lit with ultraviolet. This is the bench from the hook and Hallwachs's 1888 experiment; watch the leaves and keep in mind that only a negatively charged plate loses its charge.
