Is the photoelectric effect in contrast to classical theories? Yes, counterintuitive that energy of electromagnetic waves depends on wavelength and not on amplitude O Yes, counterintuitive that electromagnetic waves have been found to have mass and can be considered as particles with energy proportional to their frequency O No, effect well described within Maxwell's theory O No, effect well described within Newton's theory
