When accelerated electrons are direct against an anticathode in an X-ray tube, the radiation obtained has a continuous spectrum with a wavelength minimum,
min = (124 x 10-6/V) m, where V is the voltage used for accelerating the electrons. Calculate min for V= 5 x 104 volts.
(A) 1.25 Å
(B) 0.75 Å
(D) 1.00 Å
