By now, we have accumulated massive evidence that light consists of waves. We have seen the admirable success of Maxwell’s theory, which predicts, among other facts, the speed of the waves and the phenomenon of polarization. Most convincing of all are the countless optical experiments which exhibit interference and diffraction, thereby permitting accurate wavelength measurements; surely a wavelength cannot be measured unless there is a wave.
