Question
One line in the helium spectrum is bright yellow and has the wavelength $587.6 \mathrm{~nm}$. What is the difference in energy (in eV) between two helium levels that produce this line?
Step 1
63 × 10^-34 Js), c is the speed of light (3 × 10^8 m/s), and λ is the wavelength (587.6 nm). We need to convert the wavelength to meters: λ = 587.6 × 10^-9 m Now, we can calculate the energy: Show more…
