If V is the accelerating voltage, then the maximum frequency of X-rays emitted from an X-ray tube is given by
Correct answer: B. eV/h
- A. eh/V
- B. eV/h
- C. hV/e
- D. h/eV
Explanation
B is the correct option because The maximum frequency of X-rays emitted from an X-ray tube is given by the formula eV/h , where e is the elementary charge and h is Planck's constant.

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.
