Question

The minimum wavelength of X—rays produced in an X—ray tube at

1000 kV is


A) 0.0124 Å
(B) 0.124 Å

(C) 1.24 Å
(D) 0.00124 Å​

Answer 1

Answer:   (D) 0.00124 A

Explanation:

wavelenght = hc/ev

                    =  (6.626* 10^-34 ) ( 3* 10^8 ) / (1.6* 10^-19) (1000* 10^3)

                    = (D) 0.00124 A (ANSWER)
