What type of waves are produced by bombarding a tungsten target with electrons?

When electrons are accelerated and then directed towards a tungsten target, they collide with the tungsten atoms. This high-energy interaction causes the electrons to lose energy, which is emitted in the form of electromagnetic radiation. The primary type of radiation produced in this scenario is X-rays.

X-rays are a form of high-energy electromagnetic radiation, typically generated in this manner when fast-moving electrons strike a metal target. The energy loss experienced by the electrons results in the emission of X-rays as they transfer energy to the atoms of the tungsten, causing transitions in their electron shells.

Ultrasound refers to sound waves that are above the audible range for humans and do not involve electromagnetic radiation or high-energy particle interactions. Gamma rays, while they are also high-energy electromagnetic radiation, are usually produced from radioactive decay or nuclear reactions, not from electron interactions with a metal target. Infrared waves are associated with lower energy transitions, related to heat and molecular vibrations, and thus do not result from high-energy electron bombardment in the way described in this scenario.
