The threshold frequency of a material is `2xx10^14` Hz. What is its work function in eV ?

Explanation

To find the work function of a material given its threshold frequency, we can follow these steps:

### Step 1: Understand the relationship between work function and threshold frequency
The work function (φ) of a material is related to its threshold frequency (ν₀) by the equation:
\[ φ = h \nu₀ \]
where:
- φ is the work function in joules,
- h is Planck's constant (\(6.626 \times 10^{-34} \, \text{J s}\)),
