Waves - Wavelength/Amplitude/Frequency - Redshift

Pick a starting place in SDSS using constellations. This location will open up in SDSS Navigator. Record your RA and Dec.

Click on the box "Objects with spectra" and choose red boxes for several stars, galaxies and qso. For each object, click on "Explore" and then the "Interactive Spectrum" to examine the light from that object. Record the H alpha, the H beta and the H gamma wavelengths.

Our data of the range of Hydrogen lines - Blue circles = blueshifted; Red circles = redshifted
