Because the scale is arbitrary, it has no meaning by itself. WebThe explanation comes from the band theory of the solid state: in metallic solids, the electronic energy levels of all the valence electrons form bands of zillions of energy levels packed really closely together, with the electrons essentially free to …
WebThe high average power is obtained due to innovative technology that cools the inside surface of the lamp envelope by means of a spiraling water jet. The optical output between 200 and 2000 nm was measured by using a calibrated pyroelectric detector and glass color filters, and accounted for 54% of the electrical input.
