The minimum wavelength of $X$ -rays produced by an electron accelerated through a potential difference of $V$ volts is proportional to:NEET 2023 (All India)

Options:

Answer:

Solution:

Minimum wavelength means maximum energy as $E = \frac{h c}{λ}$ .
Therefore,
$e V = \frac{h c}{λ_{m i n}} \Rightarrow λ_{m i n} = \frac{h c}{e V} \Rightarrow λ_{m i n} \propto \frac{1}{V}$
