When electrons collide with the target in an X-ray machine, they primarily generate heat and produce X-rays. This occurs because the high-speed electrons, which are accelerated towards a metal target (usually tungsten), possess significant kinetic energy. Upon impact, this energy is converted in two main ways:

  1. Generation of Heat: The majority of the energy from the electrons is transformed into heat due to the abrupt deceleration and interactions with the atomic structure of the target material. This heat must be managed effectively, as it can damage the X-ray machine if not dissipated.

  2. Production of X-rays: A small portion of the electron's energy, about 1%, is transformed into X-ray photons during interactions with the target. These X-rays are the desired outcome of the process and can be harnessed for imaging applications in medical settings.

The other options involve processes that do not occur in the context of an X-ray machine's operation. While sound waves can be produced in various contexts, they are not a direct result of the interactions in an X-ray machine. Electric current involves the flow of charge, but in the context of electron collisions within the X-ray machine, the focus is on the energy release as heat and X-rays rather
