- Choose the correct statements concerning the elec- tromagnetic spectrum given off by stars. (Give ALL correct answers, i.e., B, AC, BCD...)A) If we see a blue star and a red star in a nearby star cluster, we know the red star is hotter.B) Blue photons are more energetic than red photons.C) Hot stars are much brighter than cool stars of the same size and distance from the Earth.D) Blue photons (blue light) have a longer wavelength than red photons.E) A hot star will be more red in color than a cooler star. F) All stars are the same color as our Sun.A stars wavelength is observed to be 200 nm. Calculate the approximate surface temperature of the starBriefly explain why the intensities of rotational spectral lines increase with increasing J and pass through a maximum before tailing off as J becomes large.
- Select average representative temperatures for 1) the average Earth surface, 2) the Sun, 3) a typical cloud, and 4) typical snow and calculate:a) The rate of electromagnetic energy emission for each surface in Wm-2, assuming all surfaces are blackbodies.b) The wavelength of maximum radiation in mum and determine the portion of the spectrum in which it occurs.Just wish to ask how to get E=-3KT/2 from fluence rate spectrum ? please provide details thank you very muchIf a star has a peak wavelength of 450 nm (violet). What is the corresponding frequency of this wavelength? What is the corresponding temperature? What is the photon energy for a single photon of light (450 nm)?
- What is the smallest wavelength, in nvm, of light that we can normally see?The elliptical galaxy NGC 4889 is the largest galaxy in the Coma Cluster (shown in the image below taken by the Hubble Space Telescope). After analyzing the spectrum of NGC 4889, an astronomer identifies a spectral line as being CaII (singly ionized Calcium) with a measured wavelength of 401.8 nm. The true, rest wavelength of this spectral line, measured in a lab, is 393.3 nm. a) What would be this galaxy’s recessional velocity, in km/s? b) Using a Hubble constant of ?0 = 70 km/s/Mpc, find the distance to this galaxy cluster. Give your answer in megaparsecs and in light-years. c) How would your answer to part b) differ if the Hubble constant had a smaller value? A larger value?
