In experiment of Davisson-Germer, emitted electron from filament is accelerated through voltage V then de-Broglie wavelength of that electron will be ______m.

Question

In experiment of Davisson-Germer, emitted electron from filament is accelerated through voltage V then de-Broglie wavelength of that electron will be ______m., 2 V e m h, h 2 V e m, 2 V e m h, h 2 V e m
