Question

what kind of rays are produced when a metal, such as tungsten, is bombarded with electrons moving with very high velocities?
x-rays
gamma rays
cathode rays
infrared rays

Explanation:

When high-velocity electrons strike a heavy metal like tungsten, the rapid deceleration of electrons produces high-energy electromagnetic radiation known as X-rays. Gamma rays originate from nuclear reactions, cathode rays are the incoming electrons themselves, and infrared rays are low-energy thermal radiation, so these do not match the described process.

Answer:

A. X-rays
