Given that a photon of light of wavelength 10,000 \(\stackrel{a}{A}\) has energy equal to 1.23 eV. When light of wavelength 5000 \(\stackrel{a}{A}\) and intensity \(I_{0}\) falls on a photoelectric cell, the saturation current is 4 x 10-7 amp and stopping potential 1.36 V. Then the work function is
- 0.43 eV
- 1.10 eV
- 1.36 eV
- 2.47 eV
Answer
(B) 1.10 eV
