Question 2 Question: Not complete Wien's displacement law describes the relationship between the wavelength at which the spectral intensity vs wavelength graph peaks (max) and temperature. It can be Marked out of 1.00 written as Flag question maxT = 2.898 x 10 m. K Part 1) List the stars in the image below in order of their temperature, hotter to cooler. A B C Figure 1. Three stars, A, B and C are highlighted by a coloured box around each star. A is a blue star, B is a red star and C is an orange star. The hottest star is (No answer given) + The next hottest star is (No answer given) + The coolest star is (No answer given) +Figure 1.

Before Planck came up with his expression, the Rayleigh-Jeans law S(), T) = 2nckT was used to describe black body intensity vs wavelength curves. Which of the following is true? O The Rayleigh-Jeans law predicts that the intensity will become infinite at short wavelengths. O The Rayleigh-Jeans law correctly predicts the wavelength dependence of the intensity for all wavelengths. O Planck's law correctly predicts the wavelength dependence of the intensity for all wavelengths. O The Planck relationship predicts that there will be a wavelength, at which the intensity will be maximum for each temperature.
