PHXII11:DUAL NATURE OF RADIATION AND MATTER
357727
In photoelectric experiment energy of \(2.48\,eV\) irradiates a photo sensitive material. The stopping potential was measured to be \(0.5\,V.\) Work function of the photo sensitive material is
1 \(1.68\,eV\)
2 \(2.48\,eV\)
3 \(0.5\,eV\)
4 \(1.98\,eV\)
Explanation:
According to Einstein's photoelectric equation, \(e{V_0} = hv - \phi \quad \quad \quad (1)\) where \(V_{0}\) is the stopping potential and \(\phi\) is the work function. Here, \({V_0} = 0.5\,\;V,hv = 2.48\,eV\) Substituting given values in equation (1), we get \(0.5\,eV = 2.48\,eV - \phi \) \( \Rightarrow \phi = 1.98\,eV\)
