1. The problem statement, all variables and given/known data 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? 2. Relevant equations not sure ,and would like to know. 3. The attempt at a solution tried several transmission density and it proved that the higher intensity in light the higher stopping potential % Transmission => Stopping V 100% =>0.48 66 =>0.45 45 =>0.44 Is there a formula or theory behind this behavior?
