can you clarify? do you mean the total energy the sun projects onto a sphere centered at the center of the sun is the same for any radius greater than the radius of the sun?
- Doxin 8y agoYes. The photons from the sun get uniformly emitted at the same speed in all directions (assuming spherical cows). Since there aren't any photons lost or gained the amount of energy at a certain distance from the origin must always be the same.
- teekert 8y agoIn other words, if you encapsulate the sun into a sphere, said sphere receives an equal amount of photons per hour regardless of its size, they are just spread over more surface area, hence the square term.
