The spectrum of sodium the wavelength of two bright lines are in A° |
|
Answer» Answer: The SODIUM spectrum is dominated by the bright doublet known as the Sodium D-LINES at 588.9950 and 589.5924 nanometers. From the energy level diagram it can be seen that these lines are EMITTED in a transition from the 3p to the 3s LEVELS. The line at 589.0 has twice the INTENSITY of the line at 589.6 nm. |
