A line in the Brackett series of hydrogen has a wavelength of 4052 nm. From what state did the electron originate?
n_1 = ________
In what region of the electromagnetic spectrum is this line observed?
__ gamma rays
__ X rays
Use the Rydberg equation:
1/lambda = R (1/n12 - 1/n22)
R = Rydberg constant = 1.097 x 107 m-1
lambda = wavelength in meter
n2 > n1
This solution shows how to calculate the state an electron originated in and how to figure out the region of the electromagnetic spectrum that this line is observed in.
