Hello i need help with these questions. Thank you.

A. Sketch an energy-level diagram illustrating all the possible excitations in the hydrogen atom that terminate at nfinal = 5.

B. From the spectral lines in your sketch (see part a), identify the highest energy transition. No calculation is necessary.

C. From the spectral lines in your sketch (see part a), identify the longest wavelength transition. No calculation is necessary.

2. An electron initially in the n = 7 state of a hydrogen atom relaxes and a photon with wavelength of 1006 nm is emitted.

1. What is the energy of the emitted photon?
2. what is the change in energy of the electron?
3. What is the final state?

3. If a photon is absorbed by an atom...

1. n_i >n_f
2. E_i >E_f
3. E > 0
4. E_photon < 0
5. relaxation has occurred

4. If a photon is emitted by an atom ...

1. n_i f
2. E_i f
3. E > 0
4. h =E_photon = -E
5. excitation has occurred

5. If the electron in a hydrogen atom relaxes from then = 3 state to then = 2 state, what is the energy of the emitted photon?

1. -3.025 x 10^-19 J
2. 3.025 x 10^-19 J
3. -3.630 x 10^-19 J
4. 3.630 x 10^-19 J
5. 1.089 x 10^-17 J

6. a) If you are driving a 1200 kg Honda Civic at 50.0 km/h along a city street, what is the wavelength of your car?

b) If an electron is traveling at the same speed as your car, which will have a longer wavelength, the electron or your car? (me = 9.11 x 10 kg) Justify your answer.

7. What is the de Broglie wavelength of a neutron (m_n = 1.67510²⁷ kg) traveling at a speed of 5.36 x 10⁵ m/s?

1. 2.05 x 10^-13 m
2. 7.38 x 10^-13 m
3. 7.38 x 10^-16 m
4. 1.23 x 10^-39 m
5. 3.40 x 10^-40 m
