Problem in Modren physics
Question :Suppose that you'd like to find out if adistant star is moving relative to the earth. The star is much toofar away to detect any change in its brightness as itmoves towardor away from the earth. Instead we can use the Doppler effect todetermine its relative speed. For this problem we are going to lookat the spectrallines from hydrogen, specifically the one with awavelength of 656.46 nm.(A)Suppose that you measure the light ofa star between 640 and 680 nm...

Item 4 Learning Goal: To calculate the wavelengths of the lines in the hydrogen emission spectrum Atoms give off light when heated or otherwise excited! The light emitted by excited atoms consists of only a few wavelengths, rather than a full rainbow of colors. When this light is passed through a prism, the result is a series of discrete lines separated by blank areas. The visible lines in the series of the hydrogen spectrum are caused by emission of...
