Question
When accelerated electrons are directed against an anticathode in an X-ray tube, the radiation obtained has a continuous spectrum with a wavelength minimum, ${\lambda\frac{1.24 \times 10^{- 6}}{V}}_{\min}$, where V is the voltage used for accelerating the electrons. λmin for V = 5 × 104 V is
Options
