please solve, I mainly need help with question 3. please don't copy off of other websites.

2) For a surface with an area of 2 m2, consider the radiation coming from the direction at an angle of 60 to the normal of the surface. For a time interval of 1 hour, if the radiation energy that crosses the surface from this specific direction within a solid angle of 0.1 is 7x105 J, what is the intensity of radiation? 3) If half of the intensity from question 2 is confined in the wavelength interval from 0.4 to 0.6 um, and another half in the interval from 0.6 to 1.0 um. What are the monochromatic intensities at the wavelengths of 0.5 um and 0.8 um
