A strip of Na metal is bombarded by violet light (wavelength = 410 nm) at a rate of 10,000 photons per second, which causes a steady stream of electrons to be ejected from the metal via the photoelectric effect. The minimum energy required to eject an electron from Na is 4.41 x 10−19 J. What will happen if the Na is now bombarded with red light (wavelength = 700 nm) at a rate of 10,000 photons/second?
