Question

If λ_min is minimum wavelength produced in X ray tube and λ_kα is the wavelength of λ_α line. As the operating tube voltage is increased.

(A) (λ_k – λ_min) increases

(B) (λ_k – λ_min) decreases

(C) λ_kα increases

(D) λ_ka decreases

Answer 1

Correct Answer is: (A) (λ_k – λ_min) increases

By increasing the operating voltage, l_k does not change but l_min decreases
