X-rays are produced in _ tube.
Correct answer: D. Vaccum
- A. Ar filled
- B. He filled
- C. H filled
- D. Vaccum
Explanation
An X-ray tube is a vacuum tube that is designed to generate X-rays by accelerating electrons to high speeds and then colliding them with a metal target. The tube consists of a cathode, an anode, and a vacuum chamber.

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.
