Question

Problem 5.1. Show that the total amount of energy per unit time crossing an imaginary sphere centered on the Sun with radius $r$ is equal to $f \cdot 4\pi r^2$. From the principle of the conservation of energy, argue that this quantity must equal the luminosity of the Sun: $L_\odot = f \cdot 4\pi r^2$.

Problem 5.1. Show that the total amount of energy per unit time crossing an imaginary sphere centered on the Sun with radius r is equal to f · 4π r^2. From the principle of the conservation of energy, argue that this quantity must equal the luminosity of the Sun:
L⊙ = f · 4π r^2.
