Four students were doing the photoelectric experiment with lights having different wavelengths and intensities.

If these four students are strong supporters of the classical wave model of light, then whose experiment will supposedly need the highest stopping potential?
Avinash
Of the four, Avinash and Satra seem to be working with the maximum intensity of light, which, according to the classical wave picture, should carry the maximum amount of energy, thereby ejecting electrons out with the highest kinetic energy! So naturally, Avinash and Satra have to deal with the highest stopping potential as well, although Ram and Himanshu have sources with smaller wavelengths (or higher frequencies) right? Well, that's what the wave model predicts. For this question, option b) and c) are correct.
