Question

Bohr Model - Line Spectra 2 -0.07.ww Bohr's Model - Line Spectrum in eV:E, --13.6.1-1.2.3.4. SE-EE Emitted lines Electrons in hydrogen atoms are in the n = 7 state (orbit). They can jump up to higher orbits or down to lower orbits. Emitted Spectral lines: When electrons in the higher orbits (with higher energies) jump DOWN to Lower orbits (with lower energies), energies are emitted in the form of emitted photons (light). The electrons jump from n = 7 state down to lower orbits. (a) To produce the LONGEST Emitted wavelength, what is the nf of the orbit to which the electrons jump? Enter a number Incorrect (0.0%) Submit (3 attempts remaining) What is the LONGEST Emitted wavelength (in nm)? Keep 2 decimal places. Enter a number nm Submit (5 attempts remaining) What is the energy (in eV) of the Emitted photon with the LONGEST wavelength? Since this is the energy of the photon, it should be positive. Keep 3 decimal places. Enter a number eV Submit (5 attempts remaining) (b) To produce the SHORTEST Emitted wavelength , what is the nf of the orbit to which the electrons jump? Enter a number Submit (5 attempts remaining) What is the SHORTEST Emitted wavelength (in nm)? Keep 2 decimal places. Enter a number nm Submit (5 attempts remaining) ABSORBED Spectral lines: In order for electrons in the lower orbits (with lower energies) jump UP to higher orbits (with higher energies), they must absorb energies, usually in the form of absorbed photons (light). The electrons jump from n = 7 state UP to higher orbits.

Answer 1

Emitted spectral lines a) To produce longest wavelength (omissed), DF = 6. Longest wavelength, x is RA [+ RH = Rydberg constant = 1.1810? = lower sobir= 67 22-0-7 Ś = 1.1810?
