Explanation:hope this helps
The minimum number of photons of green light that can be detected by the human eye is 6.
Given that;
E = nhc/λ
E = energy of the photon =
J
n = number of photons = ?
h = Planks constant =
Js
c = speed of light =
m/s
λ =
m
Making number of photons the subject of the formula;
n =
n = 6 photons
