The ranking of the wavelengths of the particles from largest to the smallest.

Question

A sodium atom in one of the states labeled “Lowest excited levels” in Fig. remains in that state, on average, for 1.6 * 10-8 s before it makes a transition to the ground state, emitting a photon with wavelength 589.0 nm and energy 2.105 eV. What is the uncertainty in energy of that excited state? What is the wavelength spread of the corresponding spectral line?

A certain laser produces light at a wavelength 800 nm in pulses that last 4 x 10-15 s. You should assume that uncertainties correspond to standard deviations. Give your answers with units. a) What is the energy of a single photon in the pulse? Number Units b) What is the uncertainty on the photon energy? Number Units c) What is the momentum of a single photon in the pulse? Number Units d) What is the uncertainty on the photon momentum? Number Units

The energy associated with light comes in bundles called quanta. A quantum of light energy is called a photon. What is the amount of energy associated with a photon of frequency 4.80 x10¹4 Hz? E = eV (Note the energy in electron volts; recall 1 eV = 1.602 x10-19 J) What is the amount of energy associated with a photon of wavelength 410 nm? E = eV What is the wavelength of a photon carrying 2.70 eV of energy? λ = nm (Recall 1 nm = 10-9 m)
