Which of the following properties must be there in a substance so that it can be used as a target in an X-ray tube?

Explanation

An X-ray tube is a device that produces X-rays by accelerating electrons and directing them towards a target material. When high-speed electrons collide with the target material, X-rays are produced through a process called bremsstrahlung radiation.The efficiency of X-ray production is directly proportional to the atomic number of the target material. This is because higher atomic number elements have more electrons that can be excited by the high-speed electrons, leading to a greater number of X-rays produced.Therefore, a substance with a high atomic number, such as tungsten, is an ideal target material for an X-ray tube. Additionally, the target material should have a high melting point and good thermal conductivity to withstand the high heat generated during X-ray production.
