Which of the following graphs represents the output of an X-ray?
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The given graph in option A represents the observed intensity of the X-rays emitted by an X-ray tube as a function of wavelength. The sharp peaks denote characteristic X-ray spectra. At other wavelengths, the intensity varies gradually, so that no definite line of separation can be drawn between any two of them. These X-rays are called continuous X-rays.

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.
