# the threshold frequency of cesiummetal is 4.38 x 104 Hz, calculate the kinetic energy greof an electron ejected from the surface of cesiummcn =metal when it is irradiated with light of wavelength n4-400.0 nm.dongSA G HUGI4-30. The threshold frequency of a metal can be of25ndetermined from measurements of the speed of 4-the ejected electrons.
