Modern Physics Lesson 3
... The photoelectric effect showed that a photon, or quantum of light, behaves like a particle, since it has kinetic energy (even though it has no mass). This was a VERY BIG DEAL since light had always been thought of as a wave before. Einstein proposed that photons should also have momentum, and then ...

X-ray fluorescence
X-ray fluorescence (XRF) is the emission of characteristic ""secondary"" (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science and archaeology.
