Speed of light c=3.00x10 8 m/s Planck constant h=6.63x10 -34 m2.kg/s1 eV=1.602.10-19 Joule Flame emission spectroscopy is used to analyze sodium atoms. Given that the
Speed of light c=3.00x108 m/s Planck constant h=6.63x10-34 m2.kg/s1 eV=1.602.10-19 Joule Flame emission spectroscopy is used to analyze sodium atoms. Given that the emission of sodium is measured at 300nm, the difference in energy between the excited and ground states is:
- 6.63 x 10-31 Joule
- 66.3 x 10-19 Joule
- 4.14 eV
- 6.63 x 10-19 eV
