We have voltage give as 100 V
Work done or Energy = e(x)
and
also Energy= hv
So we have,
e(x) = hv
e(x) = hc/λ
Solving for λ we get,
Hence your answer.
NOTE: here, e = charge of electron, x = potential difference i.e Voltage, v = frequency of wave, λ is the wavelength, h is plank's constant and c is speed of light.

Acceleration potential .The de Broglie wavelength
= nm
= nm=.
The de Broglie wavelength associated with an electron in this case is of the order of X-ray wavelengths.
