1. The hydrogen emission spectrum extends into the near ultraviolet region. Calculate the wavelengths associated with the two next highest energy emission lines of hydrogen beyond the Balmer series,

Identify any of the Balmer series transitions in the spectrum of the star Rigel (a typcial B-class star).

2. Explain why the "peaks" in the Rigel spectrum are actually shown as "valleys". In other words, why do we here on Earth measure a decrease in intensity at the wavelengths associated with the Balmer transitions compared with the blackbodt intensity?
