Question

Problem 34.30 The sun has a power output of 3.83 × 1026 W.

Part A How many photons does the Sun emit each second? Assume that the average value of the wavelength of light emitted by the sun is 500 nm. N =photons per second Part B Installed on your roof is a solar panel that has a surface area of 1.90 m2. How many photons from the Sun reach the panel? Assume in this part that the average value of the wavelength of light is 580 nm. Assume also that the sun emits photons equally in all directions and that photons are not scattered or absorbed by atmosphere on their way to the panel. Use the average Earth-Sun distance.
