PPT-Wave Properties of Particles

Looking back it may seem odd that two decades passed between the 1905 discovery of the particle properties of waves and the 1924 speculation that particles might show wave behavior It is one thing however to suggest a revolutionary concept to explain otherwise mysterious data and quite another to suggest an equally revolutionary concept without a strong experimental mandate The latter is just what Louis de Broglie did in 1924 when he proposed that moving objects have wave as well as particle characteristics So different was the scientific climate at the time from that around the turn of the century that de Broglies ideas soon received respectful attention whereas the earlier quantum theory of light of Planck and Einstein had been largely ignored despite its striking empirical support The existence of de Broglie waves was experimentally demonstrated by 1927 and the duality principle they represent provided the starting point for Schrödingers successful development of quantum mechanics in the previous year. Wave Pink, Wave Purple and Wave Lavender, the first flowers will appear closer to the center of the pot. 6-In.
