CHEM 1211L Lab Manual-Page 61 Atomic Spectroscopy Prelab Exercises Name: A green emission band was observed to have a wavelength of 4921 A, what is its wavelength in meters? 1. Answer A yellow emission band was observed to have a wavelength of 5876 A, what is its energy in joules? (Use Eq. 3) 2. Answer A violet emission band was observed to have a wavelength of 4026 A, what is its energy in joules? (Use Eq. 3) 3. Answer List infrared, ultraviolet, and x-ray in order of: decreasing wavelength. 4. a) increasing energy. b) Using Equation 4, what is the electron energy level transition that produces an energy of 4.84 x 101 J? (For hydrogen-like particles, n2 is 2 and ni can be 3, 4. 5, or 6 for wavelengths in the visible region of the spectrum.) 5. Answer
