In an experiment on photoelectric effect, the stopping potential is measured for monochromatic light beams corresponding to different wavelength. The data collected are as follows:
wavelength (nm): 350 400 450 500 550
stopping potential (V): 1.45 1.00 0.66 0.38 0.16
Plot the stopping potential against inverse of wavelength on a graph paper and find (a) the Planck constant, (b) the work function of the emitter and (c) the threshold wavelength .

Explanation

To solve the problem step by step, we will follow the instructions provided in the video transcript and derive the required values.

### Step 1: Data Preparation
We have the following data for wavelength (in nm) and stopping potential (in volts):

| Wavelength (nm) | Stopping Potential (V) |
|------------------|------------------------|
| 350 | 1.45 |
