(Part A) Consider a blackbody that radiates with an intensity I2 at a room temperature of 300K. At what intensity will this blackbody radiate when it is at a temperature of 400K? (Part B) At what wavelength (lamda m) would the intensity of blackbody radiation be at a maximum when the blackbody is at 2900K?
(Part C) An astronomer is trying to estimate the surface temperature of a star with a radius of 5.0x10^8 by modeling it as an ideal blackbody. The astronomer has measured the intensity of radiation due to the star at a distance of 2.5x10^13 and found it to be equal to 0.055 W/m^2. Given this information, what is the temperature of the surface of the star? Express answer in K.
