1. The Lynan alpha spectral line of hydrogen differs by 1.8 × 10<sup>-12</sup> meter in spectra taken at opposite ends of Sun's equator. What is the speed of a particle on the equator due to the Sun's rotation? (10 pts) 2. Calculate the temperature of a blackbody if the spectral distribution peaks at (I) gamma rays $\lambda = 1.50 \times 10^{-14} m$; (II) x rays 150 nm; (III) red light 640 nm

Doppler shift of a hydrogen spectral line One of the most prominent spectral lines of hydrogen is the $\mathrm{H}_{\alpha}$ line, a bright red line with a wavelength of $656.1 \times 10^{-9} \mathrm{~m}$. (a) What is the expected wavelength of the $\mathrm{H}_{\alpha}$ line from a star receding with a speed of $3000 \mathrm{~km} / \mathrm{s}$ ? (b) The $\mathrm{H}_{\alpha}$ line measured on Earth from opposite ends of the Sun's equator differ in wavelength by $9 \times 10^{-12} \mathrm{~m}$. Assuming that the effect is caused by rotation of the Sun, find the period of rotation. The diameter of the Sun is $1.4 \times 10^{6} \mathrm{~km}$.

(a) Calculate the surface temperature T of the sun (in K) by assuming that it is a spherical black body with a radius of 7 !! 10^8 m. The intensity of the solar radiation at the surface of the Earth is 1.4 !! 10^3 Wm^-2 and the distance between the Sun and the Earth 1.5 !! 10^11 m. (b) Using the value of T obtained in (a), determine the wavelength λmax at which the spectral emittance R(λ, T) of the Sun (considered as a perfect black body) has its maximum value.
