Current Attempt in Progress

When ultraviolet photons with a wavelength of $3\mathrm{.}45{10}^{-7}m$ are directed at the surface of an unknown metal in vacuum, electrons with a maximum kinetic energy of $1\mathrm{.}52$ eV are emitted from the surface. What is the work function of the metal?

$3\mathrm{.}60$ eV

$3\mathrm{.}11$ eV

$2\mathrm{.}59$ eV

$2\mathrm{.}08$ eV

$1\mathrm{.}98$ eV
