Abstract
IT is well known that the wave-theory of light fails to explain certain phenomena, and so much has been written on this subject already, that it seems at first sight unnecessary to emphasise this point. But although the main problem has not altered and no solution has been found, yet the general attitude towards this question is slowly changing, and several important new experiments have been carried out. Recently a new theory was put forward by Bohr, Kramers and Slater which would have removed many of the difficulties, but experiments by Geiger and Bothe quickly showed it to be incorrect. This theory and its refutation were not without their effect, and now the attitude is frequently held that the light-quantum theory is not merely a crude picture of certain facts, but is an important theory no further from the truth than the wave-theory. The wave-theory itself cannot be correct, but except for its greater age it has no greater claims than the light-quantum view.
