X-rays are produced by an x-ray tube with an applied potential difference of V. The spectrum of wavelengths is found to contain
A) a single wavelength.
B) all wavelengths below a maximum.
C) all wavelengths above a minimum.
D) only discrete wavelengths.

Question

Quizplus · Accepted Answer

X-rays produced by an x-ray tube have a continuous spectrum with all wavelengths above a minimum wavelength, determined by the applied potential difference. This minimum wavelength corresponds to the maximum energy of the x-rays, which is inversely proportional to the potential difference.
