What is astronomical spectroscopy?
Q: What is astronomical spectroscopy?
A: Astronomical spectroscopy is the science of using spectroscopy to determine what elements astronomical bodies are made of and how they are moving.
Q: What can spectroscopy be used for in astronomy?
A: Spectroscopy is used to help scientists study the whole spectrum of electromagnetic radiation from stars and other hot celestial objects. It can find out their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using doppler effect measurements.
Q: What is the doppler shift?
A: The doppler shift is a change in the wavelength of electromagnetic radiation caused by the movement of an object.
Q: How can spectroscopy be used to determine distant object properties?
A: Spectroscopy can be used to determine the chemical composition, temperature, density, mass, distance, luminosity, and relative motion of distant stars and galaxies.
Q: What is the relationship between spectroscopy and electromagnetic radiation?
A: Spectroscopy is used in astronomy to study the whole spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects.
Q: What is the importance of astronomical spectroscopy?
A: Astronomical spectroscopy is important because it allows scientists to determine the properties of distant objects that would otherwise be impossible to study.
Q: How can doppler effect measurements be used in astronomical spectroscopy?
A: Doppler effect measurements can be used to determine the relative motion of stars and galaxies, which can provide information on their distance and velocity.
