There is no doubt that I, also, had long been aware of the problem, i.e. producing X-ray interferences, before the inherent difficulties…

For in 1900 all electromagnetic radiation of longer wavelengths was already known at least to the extent that one could not seek…

For as long as one has no further point of reference, apart from the position of the maximum, the wavelength thus remains…

If diffraction or interference phenomena were to be sought it was therefore necessary, in accordance with the basic principles of wave theory,…

With crystals we are in a situation similar to an attempt to investigate an optical grating merely from the spectra it produces...…

For both reasons, owing to the thermal motion and to the working together of various wavelengths, factors arise which, in a similar…

Notwithstanding these major arguments the wave theory initially did not meet with complete acceptance.
