Question

Problem 1.5 Planck's law Now that we are all caught up on math, let's take those skills and put them to use on some astronomy! Planck's law is written in frequency form as 2hv3/c2 I(v,1)= env/KT – 1 Problem 1.5.1 What is the intensity of a blackbody with temperature 6000 K at a frequency of 6 x 1014 Hz? (5 points) Problem 1.5.2 Thinking about the above blackbody with a temperature of 6000 K, is the peak intensity at a higher or lower wavelength than a blackbody with a temperature of 7000 K? (5 points) Problem 1.5.3 For the two blackbodies (one with temperature T = 6000 K and one with temperature T = 7000 K) with equal emitting areas, which emits at a higher intensity at v= 1016 Hz? How about at v= 109 Hz? (5 points)
