The retina of a human eye can detect light when radiant energy incident on it is at least 4.0X10-17 J
Homework Answers
= 6.62*10^-34 J*s * (3*10^8 m/s)/600*10^-9 m = 3.3*10^-19 J
4*10^-17 J corresponds to 120 photons of that color (orange) light

incident photons (2) When monochromatic light with wavelength 496 nm is incident on a certain photo-sensitive material, photoelectrons are liberated. When violet light with wavelength 400 nm is incident on the same surface, photoelectrons are liberated but with 30% less kinetic energy than before. What is the work function of the photo-sensitive material? photo- electrons photo- sensitive material
