question 130

Multiple Choice

The Balmer series of hydrogen has a series limit (at 364.6 nm) (see Figure 3.51,Comins,Discovering the Essential Universe,6th ed.) because hydrogen in the n = 2 state:

• A) is excited to a higher discrete level by photons shorter than this wavelength.
• B) cannot absorb photons of longer wavelength.
• C) cannot absorb photons of shorter wavelength.
• D) is ionized by photons of shorter wavelength.
