  • question_answer
    An electron beam is accelerated by a potential difference V to hit a metallic target to produce X- rays. It produces continuous as well as characteristic X-rays. If \[{{\lambda }_{\min }}\] is the smallest possible wavelength of X-ray in the spectrum, the variation of log \[{{\lambda }_{\min }}\] with log V is correctly represented in:          

    A)

    B)

    C)

    D)

    Correct Answer: C

    Solution :

    [c] In X-ray tube, \[{{\lambda }_{\min }}=\frac{hc}{eV}\] In \[{{\lambda }_{\min }}=In\left( \frac{hc}{e} \right)-InV\] Clearly, \[{{\lambda }_{\min }}\] versus log V graph Slope is negative hence option [c] correctly depicts.
