Use the following information to answer the next question. The photoelectrons emitted from a surface illuminated by light with a wavelength of 491 nm have a stopping potential of 0.710 V. When the incident EMR was replaced with EMR of a different wavelength, the stopping potential was then 1.43 V. What was the work function for the surface and the wavelength of the new light? A. 2.92 x 10 J, 382 nm B. 4.05 x 10 9 J, 3.82 x 10 'm C. 1.83 eV, 869 nm D. 2.92 eV, 8.69 x 10 E
