The work function for a certain metal is 4.2 eV. Will this metal give photoelectric emission for incident radiation of wavelength 330 nm?

Explanation

`phi=4.2eV`
`E=h upsilon=h(c )/(lambda)=(6.6xx10^(-34)xx3xx10^(8))/(330xx10^(-9))J=(6.6xx10^(-34)xx3xx10^(8))/(330xx10^(-9)xx1.6xx10^(-19))=3.75eV`
`phi_(0) gt E`, so not possible.
