Target material used in an X-ray tube must have the following properties
Correct answer: A. high atomic numbers and high melting point
- A. high atomic numbers and high melting point
- B. high atomic numbers and low melting point
- C. low atomic number and low melting point
- D. high atomic number only
Explanation
A is the right optionThe target material in an X-ray tube should have high atomic numbers to enhance X-ray production through interactions with fast electrons. Additionally, it should have a high melting point to withstand the high temperatures generated during the X-ray production process.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
