Lamps are divided into families based on the pressure of gas, and whether or not the cathode is heated. Hot cathode lamps have electrodes that operate at a high temperature and are heated by the arc current in the lamp. The heat knocks electrons out of the electrodes by thermionic emission, which helps maintain the arc. In many types the electrodes consist of electrical filaments m… Web19 mrt. 2011 · More answers.

WebBut if the spectrum also contains helium lines, then it is a B star, whereas if it contains lines of ionized iron and other metals, it must be a G star. If you look at Figure 3, you can see that you, too, could assign a spectral class to a star whose type was not already known. Web31 jul. 2024 · Alpha Radiation (α Rays) Alpha rays (or alpha particles or alpha radiation) are a form of radiation emitted by highly ionized and poorly penetrating particles.
