Expert Solution
Step 1
The electronic transition which represents the shortest wavelength has to be identified.
Step 2
The formula to calculate the wavelength of a transition is as follows:
Where,
The wavelength of the transition
R is Rydberg Constant
The initial orbit of an electron is n1
The final orbit of an electron is n2
So, the wave length is directly proportional to the square of electronic sate.
So, greater the value of
Smaller will be the value of wavelength.
