Star and Power emit!

  1. Oct 11, 2006 #1
    A star has radius R=1.90x10^9 m and surface temperature T=15,200K. How much power does it emit in the range 500 nm < lamda < 510 nm?

    It is what it is. Can you use the information from the link I posted, or your text, and the surface area of the star to find the answer?
