Discuss the Brief History of Time and Universe by Stephen Hawking
The Brief History of Time The Brief History of Time and Universe by Stephen Hawking The most difficult question that scientists, philosophers and religious leaders try to find answers to regards the origin, purpose and fate of the universe. People and nations invest a lot of money and time in research activities to establish the […]
Using the material presented in lecture video 9, explain briefly why the sky appears blue during the daytime and why clouds appears white or gray during the daytime.
1) List the five chief types of radiation in order of increasing (note the word, increasing) wavelength. Use the internet to find a typical wavelength in meters of each of the five types. (Do not give ranges – give specific values in units of meters.) Then find out what object (e.g., basketball, desk, person) would […]
Using the procedures outlined in Steps 1 and 2 above, examine the spectra of these objects: “3C 215”, “3C 212”, and “3C 9”.
Using the procedures outlined in Steps 1 and 2 above, examine the spectra of these objects: “3C 215”, “3C 212”, and “3C 9”. They’re quasars – and are so far away from Earth that you need to use the emission line labeled “Mg II 2799” to track their redshift. Note also their morphologies as they […]
Figure out how fast the gas clouds are moving in units of kilometers per second.
The width of an emission line is usually determined by how fast the light-emitting gas clouds are moving – in this case, how fast they’re orbiting around a supermassive black hole. Measure the width of the [S II] line pair in Angstroms by first measuring the wavelength of the right edge with your cursor, then […]
Describe the difference in appearance of the emission lines between NGC 3862 and 3C 236.
(a) Go again to the Navigate tool, and this time enter into the “name” box “3C 236” – and again look at the interactive spectrum in the Explore tool. Zoom in again to examine the five emission lines as you did for NGC 3862 above – but notice this time that the lines are redshifted […]
