Answer» Photon having energy equivalent to the binding energy of $4^{t h}$ state of $H e^{+}$ atom is used to eject an electron from the metal surface of work function 1.4 eV. If electrons are further accelerated through the potential difference of $4 V$ then the minimum value of De - broglie wavelength (in $o A$ ) associated with the electron is: (Given $\sqrt{174.72} = 13.24$ , take $h = 6.62 \times 10^{- 34} J s$
