The intensity of X-rays from a Coolidge tube is plotted against wavelength λ as shown in the figure. The minimum wavelength found is λC and the wavelength of the Kα line is λK. As the accelerating voltage is increased
  • a)
    λK - λC increases
  • b)
    λK - lC decreases
  • c)
    λK increases
  • d)
    λK decreases
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
The intensity of X-rays from a Coolidge tube is plotted against wavele...
KEY CONCEPT :
In case of Coolidge tube
Thus the cut off wavelength is inversely proportional to accelerating voltage. As V increases, λc decreases. λk is the wavelength of K line which is a characteristic of an atom and does not depend on accelerating voltage of bombarding electron since λk always refers to a photon wavelength of transition of e from the target element from 2 → 1.
The above two facts lead to the conclusion that λk – λc increases as accelerating voltage is increased.
