The maximum KE of photoelectrons emitted from a cetain metallic surface is 30 eV when monochromatic radiation of wavelength lamda falls on it. When the same surface is illuminated with light of wavelength 2lamda , the minimum KE of photoelectrons is found to be 10 eV. (a) Calculate the wavelength lamda and (b) determine the maximum wavelength of incident radiation for which photoelectric emission is possible.
