Problem

An electron is accelerated from rest through a potential difference

V

so that its associated de Broglie wavelength becomes

0.10\,\text{nm}

. (a) Calculate the value of

V

. (b) Light having the same wavelength

0.10\,\text{nm}

is used in a double–slit experiment with slit separation

d = 0.50\,\mu\text{m}

and screen distance

D = 1.0\,\text{m}

. Determine the spacing between adjacent bright fringes on the screen. a. (a) – b. (b) –
