Answer :
The Wavelength is 604 nm for the light when the energy is 3. 29 × 10-19 j for a single photon.
Wavelength is referred to as the separation between the corresponding points of two successive waves represents it. The SI wavelength unit is the metre.
We have given that the energy of photon is 3.29 × 10^-19 J/atom.
The formula to calculate wavelength is :
λ = hc / E
Where, λ = wavelength,
h= Plank's constant = 6. 626 × 10^-34 Js,
c = 3 × 10^8m/s
E = Energy of photon
Substituting the values in formula :
λ = (6.626×10^-34 Js) × (3×10^8 m/s) / 3.29×10^-19 J/atom
λ = 604 nm
