Experimental Study of Photoelectric Effect

प्रकाशवैद्युत प्रभाव का प्रायोगिक अध्ययन

In this Class 12 Physics topic from Chapter 11, Dual Nature of Radiation and Matter, students investigate the photoelectric effect through an experimental setup. They learn how light frequency and intensity affect photoelectron emission, measure stopping potential and threshold frequency, and relate observations to Einstein’s photoelectric equation. The topic also develops skills in recording readings, interpreting graphs, estimating the work function, and applying suitable experimental precautions.
