Electrons in hydrogen-like atoms (Z=3) make transitions from the fifth to the fourth orbit and from the fourth to the third orbit. The resulting radiations are incident normally on a metal plate and eject photoelectrons. The stopping potential for the photoelectrons ejected by the shorter wave length is 3.95 V. The work function of the metal =x eV. Then the value of x is _______.Rydberg constant=1.094×107 m−1

1.	Electrons in hydrogen-like atoms (Z=3) make transitions from the fifth to the fourth orbit and from the fourth to the third orbit. The resulting radiations are incident normally on a metal plate and eject photoelectrons. The stopping potential for the photoelectrons ejected by the shorter wave length is 3.95 V. The work function of the metal =x eV. Then the value of x is _______.Rydberg constant=1.094×107 m−1
Answer» Electrons in hydrogen-like atoms $(Z = 3)$ make transitions from the fifth to the fourth orbit and from the fourth to the third orbit. The resulting radiations are incident normally on a metal plate and eject photoelectrons. The stopping potential for the photoelectrons ejected by the shorter wave length is $3.95 V$ . The work function of the metal $= x eV$ . Then the value of $x$ is _______. $Rydberg constant = 1.094 \times 10^{7} m^{- 1}$
