Target material used in X-rays tube must have following properties:
Correct answer: A. High atomic number and high melting point
- A. High atomic number and high melting point
- B. High atomic number and low melting point
- C. Low atomic number and low melting point
- D. Coherent beam of light
Explanation
Target materials in X-ray tubes should have a high atomic number because X-ray production is more efficient when interacting with high atomic number elements. Target materials should also have a high melting point because the process of producing X-rays can generate significant heat, and a high melting point material can withstand this heat without melting or vaporizing. So, option (a) "High atomic number and high melting point" is the correct choice for target materials used in X-ray tubes.

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.
