Electrons in an X-ray tube are accelerated by a potential difference of 5.0 kV. If an electron produces one photon on impact with the target, what is the minimum wavelength of the resulting X-rays?
(consider h = 6.626 * 10^-34 Js and e = 1.6 * 10^-19 C)

Question

Accepted Answer

Correct Answer: (B) 0.124 nm The minimum wavelength of X-rays produced is given by \lambda_min = hc / (e V). Substituting h = 6.626 * 10^-34, c = 3 * 10^8, e = 1.6 * 10^-19, and V = 5000 V yields \lambda_min = 0.124 nm.
