Use the following information to answer the next two question. Energy Level Diagram of a Hydrogen Atom - 0.54 eV - 0.85 eV - 1.51 ev n = 5 n = 4 n = 3 - 3.40 e V n = 2 - 13.6 eV n = 1 9. If a hydrogen electron is excited to the 5th energy level, the longest wavelength that can be emitted is A. 2.30 x 106 m B. 9.51 x 10-8 m C. 4.01 x 106 m D. 6.42 x 10-25 m 10. The hydrogen gas in the previous information box is placed in a spectral tube and a power source is connected across the anode and cathode of the tube. The voltage across the tube is initially set a zero volts and is then gradually increased. At what minimum voltage will the gas in the tube emit 6 different spectral lines? A. 12.75 V B. 10.20 V C. 12.09 V D. 2.55 V Numerical Response #2 Northern lights are often observed in Alberta skies. They occur as a result of a collision between electrons from the solar wind and oxygen atoms in the upper atmosphere. The oxygen atoms are excited after collision. The most common color, green, has a wavelength of 460 nm. To produce this color, the electrons must be traveling with a minimum speed, expressed in scientific notation, of a.be x 10d m/s. The values of a, b, c, and d are (Record all four digits of your answer on the answer sheet.) , and * * *
