(a) (b) Calculate the maximum kinetic energy of an electron ejected from a sodium surface whose work function is W =2.28 eV when illuminated by light of wavelength 476nm. Express your result in terms of electron volts. Kmax Given that some metals have a work function as low as 1 eV, can radio waves (f=1 MHz) eject electrons from metallic surfaces? Answer by using a calculation.
