(see the attached image); I thought this was related to binding energy but otherwise I can’t think of another way to do this.
When light of frequency \(1.30 \times 10^{15} \, \text{s}^{-1}\) shines on the surface of cesium metal, electrons are ejected with a maximum kinetic energy of \(5.2 \times 10^{-19} \, \text{J}\).

Calculate the wavelength of this light in nm.
