Explain how we use spectral absorption and emission lines to determine the composition of a gas.
What is the main reason that the spectra of all stars are not identical? Explain.
Star X has lines of ionized helium in its spectrum, and star Y has bands of titanium oxide. Which is hotter? Why? The spectrum of star Z shows lines of ionized helium and also molecular bands of titanium oxide. What is strange about this spectrum? Can you suggest an explanation?
Hydrogen accounts for about 75% by mass of the matter at the surfaces of most stars. However, the absorption lines of hydrogen are strongest (of highest intensity) in the spectra of stars with a surface temperature of about 9000 K. They are weaker in the sun spectrum and are essentially nonexistent in very hot (temperatures above 25,000 K) or rather cool (temperatures below 3500 K) stars. Speculate as to why surface temperature affects the hydrogen absorption lines that we observe.
Photons of a certain infrared light have an energy of 1.21X 10^-19 J. What is the frequency of this IR light? Use ? = c/f to calculate its wavelength in nanometers.
10:49 LTE O < All iCloud Imagine that you are observing a star and you find the wavelength of peak emission for the star to be 400 nm. What would the wavelength of peak emission be for a new star that has a surface temperature that is a quarter of the original star? Using the same pair of stars from the first question, ● how does the luminosity (the energy output) of each star compare if we assume that both stars are the same size? (Please provide a specific factor or proportion) What type of radiation/light (from the electromagnetic spectrum) is each star emitting? Now imagine that we determine that the wavelength of peak emission of the original star was determined to be bluer than it should be based on other observations. Would this indicate that the star is moving towards us or away from us relatively speaking through space? 0

Which of the following statements are TRUE about the Sun's spectrum, which is shown in this image? Brightness 2.5 3.5 0 200 Sun's Spectrum vs. Thermal Radiator of a single temperature T = 5777 K peak spectrum of Sun spectrum of T = 5777 K blackbody emission spectrum (continuum) absorption lines 400 600 800 1000 1200 1400 1600 1800 Wavelength (nanometres) 2000 The spectrum shows the presence of many sunspots. The overall shape is consistent with a continuous spectrum emitted by a blackbody. The spectrum shows that the Sun emits light of all colors equally, which is why we see it as white. The spectrum shows that the Sun emits some light in ultraviolet wavelengths. The spectrum peaks in infrared wavelengths.
