Asked in Premeth Test 17 — Atomic Spectra (physics)Moderate

In X-rays, λmin corresponds to:

Correct answer: B. Continuous x-rays

  • A. Characteristic x-rays
  • B. Continuous x-rays
  • C. Both A and B
  • D. None of the above

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.
