IB Physics: Teacher Notes: Light from stars

The way this topic builds up is quite fascinating but it is easy to lose the thread. We start by measuring how far away the star is using some simple geometry, then by measuring the spectrum of light that we receive we can measure the temperature of the star if we know the temp. then we can calculate the power emitted per unit Area. From the light received we can also find the power received at the earth and if we know...
