\textbf{175.} The work function of a metal is $4.14\,\text{eV}$. What is the maximum wavelength of light to eject electrons from the surface of this metal in nanometers?
$$\left(h = 4.14\times10^{-15}\,\text{eV.s} \text{ and } C = 3\times10^{8}\,\frac{\text{m}}{\text{s}}\right)$$
$$300 \;(1) \qquad 400 \;(2) \qquad 500 \;(3) \qquad 600 \;(4)$$
