Problem Set 3: Solutions
... With the given photon frequency of 1 MHz, we find P ∼ 10−21 W, a negligible amount of power. For photons of visible light, in the 1015 Hz range, the power is ∼ 10−12 W, which is close to the limit of human vision. With dark-adapted scotopic vision, we detect about 8 × 10−11 W/m2 of green light (550 ...

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.
