... 2. Note: Be sure that the wire loop is correctly matched to the correct chemical before using it! a. If the chemical (salt) is solid, moisten the wire loop in some distilled water. Then dip the loop in the solid chemical so that some of the chemical sticks to the loop of the wire. b. If the chemical ...

... In order to generate a single photon, one may consider using a single microscopic emitter, e.g., a single atom. When an atom makes a transition between two internal states, energy conservation ensures that it will emit exactly one photon with a frequency that corresponds to the energy difference bet ...

... 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.
