The average intensity of the full moon is \(2.92 \times {10}^{-4} W/{m}^{2}\). Approximately how many photons enter the eye per second whenever we look at the full moon on a clear night?

**Assumptions**

1) The area of the pupil is \(3 \times {10}^{-5} {m}^{2}\)

2) The wavelength of the moonlight is 550 nanometers
