Question

What is the de broglie wavelength of an electron accelerated through a potential difference of 100v?

Answer 1

$heya \: your \: answer \: is \: here \\ potential \: differenvce = 100v \\ \\ de \: broglie \: wavelength = \frac{12.27}{ \sqrt{v} } \\ = \frac{12.27}{ \sqrt{100 } } \\ = \frac{12.27}{10 } = 1.227nm$
