Question

What is the difference in energy levels of the sodium atom if emitted light has a wavelength of 589nm

Answer 1

Dear Student,

◆ Answer -

∆E = 3.9×10^-40 J

● Explaination -

Difference in energy levels of the sodium atom is calculated by -

∆E = hν

Substitute ν = 589 nm = 589×10^-9 m,

∆E = 6.626×10^-34 × 589×10^-9

∆E = 3.9×10^-40 J

Therefore, the difference in energy levels of the sodium atom is 3.9×10^-40 J.

Thanks dear. Hope this helps you...
