Choosing one value of temperature, plot the inverse-square law dependence of expected intensity vs distance to the blackbody. Think about what part of the graph should have more experimental points to accurately predict the correct shape of the curve. \emph{Reminder}: in all theoretical formulas the temperature is measured in Kelvins. \section*{2.
