⚠️ Common Exam Traps & Conceptual Pitfalls

Students often assume that photons from different X‑ray processes must have different frequencies or energies, forgetting that $E=hc/\lambda$ fixes both solely by wavelength. Remember: identical wavelength ⇒ identical frequency and energy; only the generation mechanism (bremsstrahlung vs. atomic transition) can differ.

Consider a photon of continuous X-ray and a photon of characteristic X-ray of the same wavelength. Which of the following is/are different for the two photons?

Multiple Choice Options

  • A Frequency
  • B Energy
  • C Penetrating power
  • D Method of creation

Step-by-Step Verified Solution

**Answer:** (d) Method of creation. **Step-by-Step Explanation:** Continuous X-rays are created by bremsstrahlung, while characteristic X-rays are created by atomic transitions. Frequency, energy, and penetrating power can be the same.
