particles - Prof.Dr.Ümit Demir
... He found that the scattered x-rays had a slightly longer wavelength than the incident x-rays, and hence the energies of the scattered rays were lower. The amount of energy reduction depended on the angle at which the x-rays were scattered. The change in wavelength between a scattered x-ray and an in ...

The Wave-Particle Duality for Light So is Light a Wave or a Particle
... The wave particle duality is an underlying principle of the Universe. The complete description of an electron or a photon requires both its wave and particle aspects. If two concepts are complementary, an experiment that clearly illustrates one concept will obscure the other. For example, an experim ...
