what is the relationship between stopping potential and the intensity of light?

[tnecniv]

The higher the intensity of the light we will get a higher stopping potential.
Why is that so? is there any theory and formula to justifiy this behavior?

How is wavelength affecting the intensity of light?

Please advise.

Thank You

Are you sure a higher intensity of light leads to a higher stopping potential? That is contrary to the photoelectric effect!
The wavelength and intensity of light are independent properties.
