WebX-rays are electromagnetic waves with high energy. They are produced in a vacuum-filled tube, X-ray tube. An X-ray tube is an evacuated glass envelope within which a coiled tungsten filament [1] (the cathode) acts as a source of electrons. A low voltage [2] heats the filament, "boiling" electrons off its surface. WebThe Photoelectric Effect is an important phenomenon in physics as well as in everyday life. Einstein was not the first to observe the Photoelectric Effect but he was the first to explain it and his 1905 paper earned him the 1921 Nobel Prize in Physics. Understanding the Photoelectric Effect not only helps us understand the dual wave and ...
