The work function of cesium is 2.14 eV. The threshold frequency of caesium is:
$5.16 \times 10^{19} H z$
$5.16 \times 10^{16} H z$
$5.16 \times 10^{14} H z$
$5.16 \times 10^{18} H z$

Here, $ϕ_{0} = 2.14 e V$

$υ_{0} = \frac{ϕ_{0}}{h} = \frac{2.14 \times 1.6 \times 10^{- 19}}{6.63 \times 10^{- 34}} = 5.16 \times 10^{14} H z$
