What radiation category do the x-rays belong to? | Electromagnetic radiations. |
What is an x-ray photon? | A samll bundle of pure energy with wave-like properties. |
How are x-rays produced in the x-ray tube? | High speed electons interacting with the nucleus of the target atoms giving off radiation. |
The target material(in the anode) for diagnostic tube is? | Tungsten |
