Question

b) See the raw data below and perform a proper numerical integration to find the intensity of sunlight (W/m2) hitting the satellite.

c) Use numerical integration of this data set to find the intensity of visible light that is hitting the satellite.

3. Numerical integration Graph Title: The spectral intensity of sunlight hitting a satellite that is orbiting above the earth's atmosphere 2.0 1.5 1.0 0.5 0.0 1000 3000 2000 4000 Wavelength (nm) a) Make a table that lists the average spectral intensity near 200 nm, 400 nm, 600 nm, 800 nm etc. Use approximate numbers don't worry about high precision. Use this table to estimate the intensity of sunlight W/m2) hitting the satellite.

Explanation / Answer

Wavelength                           Spectral Intensity

200                                                  0(No data point for this wavelength in graph)

400                                                 0.8W/m2/nm

600                                                  1.8W/m2/nm

800                                                  1.2W/m2/nm
