Card 1
Question: What are X-rays?
Answer: X-rays are a form of electromagnetic radiation with wavelengths ranging from approximately 0.01 to 10 nanometers, corresponding to frequencies from 30
Card 2
Question: What is the primary device for generating X-rays?
Answer: The primary device for generating X-rays is the X-ray tube.
Card 3
Question: How does an X-ray tube produce X-rays?
Answer: An X-ray tube produces X-rays by accelerating electrons to high speeds and then abruptly decelerating them upon impact with a metal target.
Card 4
Question: What are the main components of an X-ray tube?
Answer: The main components of an X-ray tube are the cathode, the anode, and a high-voltage power supply, all enclosed within an evacuated glass or metal enve
Card 5
Question: What is the purpose of the evacuated envelope in an X-ray tube?
Answer: The evacuated envelope prevents electron scattering by air molecules and protects the internal elements, as well as preventing oxidation of the filame
Card 6
Question: What is the cathode in an X-ray tube?
Answer: The cathode is the negative electrode and serves as the source of electrons.
Card 7
Question: What material is typically used for the cathode filament?
Answer: The cathode typically consists of a small coil of tungsten wire, known as a filament.
Card 8
Question: How are electrons emitted from the cathode filament?
Answer: When an electric current passes through the filament, it heats up, causing electrons to be emitted from its surface through a process called thermioni
Card 9
Question: What is the function of the focusing cup in an X-ray tube's cathode?
Answer: The focusing cup is a negatively charged metal cup that electrostatically focuses the emitted electrons into a narrow beam directed towards the anode.
Card 10
Question: What is the anode in an X-ray tube?
Answer: The anode is the positive electrode and the target where X-rays are produced.
