Threshold frequency of a certain metal for photoelectric emission is `5xx10^(14)Hz`. Calculate its work function.

Explanation

To calculate the work function of the metal given its threshold frequency, we can use the formula:

\[ \text{Work Function} (\phi) = h \cdot f_0 \]

where:
- \( h \) is Planck's constant, approximately \( 6.626 \times 10^{-34} \, \text{J s} \)
