The work function for a certain metal is 4.2eV. Will this metal give photoelectric emission for incident radiation of wavelength 330nm? Given, charge on electron, `e=1.6xx10^(-19)C, c=3xx10^(8)m//s, h=6.62xx10^(-34)Js`.

Explanation

To determine if the metal will exhibit photoelectric emission when exposed to radiation of wavelength 330 nm, we need to follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values**:
- Work function of the metal, \( \phi_0 = 4.2 \, \text{eV} \)
- Wavelength of incident radiation, \( \lambda = 330 \, \text{nm} \)
- Planck's constant, \( h = 6.62 \times 10^{-34} \, \text{Js} \)
