| Jun 21, 2021 at 21:31 | comment | added | FGSUZ | It is the definition of solid angle. It's a generalization of $\theta=s/r$, just $\Omega=A/r^2$. You're not measuring areas, you want another thing, which is related to them. As for the second question, you can compute the first integral directly, without reducing it to the sphere, but it is harder... | |
| Jun 21, 2021 at 15:20 | comment | added | Ariel Yael | Hi! Why do we divide by $r^2$? Just in order to keep the solid angle unit-less or is there another reason? Also, if the proof doesn't use solid angles, how is the relation \begin{equation}\frac{\Delta A \textrm{cos}\theta}{\Delta a}=\left(\frac{R}{r}\right)^2.\end{equation} Recieved? | |
