Question 1 **Transcription of the Image for Educational Website:****Questions:**1. **Using a UV-Vis Spectrometer, you observe a hydrogen emission line at 486.2 nm. Calculate which electronic transition (e.g. 9→7) produces this line. Show your work.** *Instructions: Utilize the Rydberg formula for hydrogen emission lines to determine the change in the principal quantum number that corresponds to the observed wavelength.*2. **Calculate the energy change (in J) if a hydrogen electron moves from the n = 6 level to n = 3 level.** *Instructions: Use the formula for the energy of a photon and the Rydberg equation to find the energy change associated with this electron transition. Remember to convert from electron volts (eV) to joules (J) if necessary.*3. **What is the wavelength (in nm) associated with the transition observed in question 2? Does this wavelength fall in the ultraviolet, visible, or infrared region?** *Instructions: Calculate the wavelength using the transition's energy difference and compare it to the electromagnetic spectrum ranges to identify its region.***Note:** Ensure you apply proper calculation methods and include all needed steps to enhance understanding. Consider using diagrams of electron transitions in hydrogen to support the explanations if available.

» Significant Figure Rules 01 >> 02 >> 03 >> 04 >> 05 >> All nonzero digits are significant. Zeros that appear between other nonzero digits are always significant. Zeros that appear in front of all of the nonzero digits are called left-end zeros. Left-end zeros are never significant. Zeros that appear after all nonzero digits are called right-end zeros. Right-end zeros in a number that locks a decimal point are not significant. ▬▬▬ 美銀銀時 ☐☐ Right-end zeros in a number with a decimal point are significant. This is true whether the zeros occur before or ofter the decimal point. 237 has three significant figures. 1.897 has four significant figures. 39,004 has five significant figures. 5.02 has three significant figures. 0.008 has one significant figure. 0.000416 has three significant figures. 140 has two significant figures. 75,210 has four significant figures. 620.0 has four significant figures. 19.000 has five significant figures.
