Lab 10 – Rotation of Saturn

Laboratory - No Radial motion Laboratory Spectrum Spectral Lines Match Laboratory - No Radial motion Earth Distant Star Radial Velocity = 0 Blueshift Radial Velocity - Redshift Radial Velocity + o 

Spectroscope Slit Light from here Red Shifted Light from here Blue Shifted No Doppler Shift From this Light

V A Saturn B V o A B 

 (mm) = Bottom Distance – Top Distance Reference Line Bottom  (mm) = Bottom Distance – Top Distance

Finding the Rotation Period of Saturn Distance = Velocity X Time V Distance = Equatorial Circumference = R Time = Rotation Period Saturn
