Final answer:
The electron beam of the television camera tube is synchronized with the television viewing monitor. CRT televisions use a high-voltage electron beam to stimulate screen phosphors and create images, potentially generating x-rays, but are designed with shielding for safety.
Step-by-step explanation:
The electron beam of the television camera tube is synchronized with the television viewing monitor. Synchronization ensures that the electron beam is in harmony with the scanning process of the display, allowing the images captured by the camera tube to be displayed correctly on the monitor. In CRT (Cathode Ray Tube) televisions, an accelerating potential of about 30-kV is used to propel electrons toward the screen, which then stimulate phosphors to emit light and create the images we see. It is plausible to expect that in such a process, x-rays could also be generated due to the high-energy collisions occurring inside the CRT. However, the design of CRTs typically includes adequate shielding to protect users from any potential x-ray emission.
When considering the velocity of electrons in television sets, particularly in older-style CRT TVs, you would find that electrons are accelerated to relativistic speeds. This acceleration and control of the electron beam are what allow the television to display an image on the screen, as the electrons stimulate the fluorescent layer to produce light in precise locations.
