Analyse information to predict the surface temperature of a star from its intensity/wavelength graph

  • At a temp – constant but not even output – particular intensity peaks for a particular temperature
  • Shifts shorter with higher temperature
  • Described using λmaxT = W (λmax = frequency of max output (m), T = temperature (K), W = constant (2.9x10-3 mK)
  • Temperature can be determined by intensity-wavelength graph
