work function of sodium is 2.35 eV what is threshold wavelength and frequency of light that causes the photoelectrons to be emitted , what is the maximum kinetic energy of photoelectrons if radiation of 1000 A° falls on metal surface ? calculate the stopping potential for radiation. |

Answer» Answer: Explanation:hc÷threshhold wavelength= work function so wavelength= 1240÷2.35=527nm. Also frequency= 5.69×10*15 and KEmax = 10.05 EV and stopping POTENTIAL is 10.05 V |
