Final answer:
False. X-ray tubes are actually quite efficient in their production of radiation.
Step-by-step explanation:
An x-ray tube is not very efficient in its production of radiation - False.
X-ray tubes are actually quite efficient in their production of radiation. They work by accelerating electrons through a high voltage, which gives the electrons significant kinetic energy. When these accelerated electrons strike the anode, they convert their kinetic energy into a variety of forms, including thermal energy and X-ray photons. Some of these X-ray photons obtain the kinetic energy of the electrons and are emitted as X-rays. Therefore, X-ray tubes efficiently produce X-ray radiation.
