The ejection of the photoelectron from the silver metal in the photoelectric effect experiment can be stopped by applying the voltage of 0.35 V when the radiation 256.7 nm is used, Calculate the work function for silver metal.

Explanation

To calculate the work function for silver metal in the photoelectric effect experiment, we will follow these steps:

### Step 1: Calculate the energy of the incident photon
The energy of a photon (E) can be calculated using the formula:
\[ E = \frac{hc}{\lambda} \]
where:
- \( h \) is Planck's constant (\( 6.626 \times 10^{-34} \, \text{J s} \))
- \( c \) is the speed of light (\( 3 \times 10^{8} \, \text{m/s} \))
