Question

Light is incident on a metallic plate having work function $110 \times 10^{-20} \mathrm{~J}$. If the produced photoelectrons have zero kinetic energy then the angular frequency of the incident light is $\_\_\_\_$ $\mathrm{rad} / \mathrm{s}$ $\left(\mathrm{h}=6.63 \times 10^{-34} \mathrm{~J} . \mathrm{s}\right)$

Select the correct option:

$1.04 \times 10^{13}$

$1.66 \times 10^{15}$

$1.66 \times 10^{16}$

$1.04 \times 10^{16}$
