is the difference between the wavelength of k_ line and the minimum wavelength of the continuous X-ray spectrum when the X-ray tube is operated at a voltage V . If the operating voltage is changed to V / 3 , then the above difference is ^ . Then
Options
- A^ =5
- B^ =4
- C^ =3
- D^ < 3
Correct answer
C. ^ =3
Step-by-step solution
aligned & We know eV = h c V V^ = ^ & V V / 3 = ^ & ^ =3( ) aligned
