Web21 de fev. de 2014 · Cathode rays travel in a straight line. This was confirmed with a Maltese cross covered with phosphor that illuminates with radiation. As voltage is applied between the cathode and the anode, the cathode rays emitted struck the metal Maltese cross used, creating a very sharp image of the same cross at the end of the tube. Web10 de mar. de 2024 · The cathode rays are emitted normally from the surface of the cathode irrespective of the position of the anode. They travel at a speed of about 10 7 to 10 9 m/s. They travel in straight lines and cast sharp shadows of objects in their paths. They are able to produce fluorescence and phosphorescence in many substances when they … WebAnode rays are radiations that are positively charged and made up of particles with charges that are equal in magnitude but reverse in sign to the electron’s. They can also be described as a beam of positive ions produced by certain types of gas discharge tubes. An anode ray particle has a mass which is equal to 2000 times of an electron. high white blood cell count causes in adults

"WebCharacteristic X-ray. Characteristic X-rays are emitted when outer- shell electrons fill a vacancy in the inner shell of an atom, releasing X-rays in a pattern that is "characteristic" to each element. Characteristic X-rays were discovered by Charles Glover Barkla in 1909, [1] who later won the Nobel Prize in Physics for his discovery in 1917. " - How cathode rays are formed
