What is the photoelectric work function for a metal if the threshold wavelength for the metal is `3.315 xx 10^(-7)`m ?

Explanation

To find the photoelectric work function (φ) for a metal given its threshold wavelength (λ₀), we can use the formula:

\[ \phi = \frac{hc}{\lambda_0} \]

Where:
- \( h \) is Planck's constant, approximately \( 6.63 \times 10^{-34} \, \text{J s} \)
