1. The problem statement, all variables and given/known data A standard candle has radiant intensity equal to 1/683 W/sr. [The unit of measurement is watts per steradian. The steradian (sr) is the standard unit for solid angles: If a patch on the surface of a sphere of radius r has area A, then the solid angle subtended by the patch at the center of the sphere is A/r^2. The solid angle of an entire sphere is 4π because the area is 4πr^2.] a) What is the energy flux density (power per unit area) at a distance of 1.06 meters from the candle? b)What is the candle power of a 75 watt light bulb? 2. Relevant equations I figured out the power to be 1.84E-2 W 3. The attempt at a solution I'm not sure how to solve this one.
