The kinetic energy of an ejected electron depends on the frequency of the incident monochromatic radiation. The higher the frequency, the greater the kinetic energy of the ejected electron. This relationship is described by Einstein's photoelectric equation: \(KE=hf-\Phi \), where \(KE\) is kinetic energy, \(h\) is Planck's constant, \(f\) is the frequency of the light, and \(\Phi \) is the work function of the metal.
The kinetic energy of an electron ejected from a metal surface exposed to monochromatic radiation depends on the at _____?
