Answer:
Thus, the minimum number of photons per second is 77.34
Explanation:
Light intensity,
= 
Pupil has a diameter, d = 8.5 mm
= 8.5 x
m
Radius of the eye, r = 4.25 x
m
∴ Area of the eye, A = 
= 
= 
Let
be the minimum number of photons.
Therefore,
=
x A
=
x 
=
W
Thus the minimum number of photons is given by

where E = 
= 
= 
Therefore,
= 
= 77.34 photons per second
Thus, the minimum number of photons per second is 77.34
