The potential difference applied to an X-ray tube is V. The ratio of debroglie wavelength of electron to the minimum wavelength of X-ray is directly proportional to

Options:

Answer:

Solution:

$λ_{d B} = \frac{h}{2 m e V} \propto V^{- 1/2}$

$λ_{m i n} = \frac{h c}{e V} \propto V^{- 1}$

Ratio $\propto V^{- 1/2} / V^{- 1} = V^{1/2}$ .
