The number of submissions ramaining for each question part only changes if you submit or change the answer Quantum States for the Visible Hydrogen Atomic Emission Spectrum Assignment Scoring Your last submission is used for your score. 1. -12 points UCSCGenChemL1 6.RQ.001 My Notes A student records the following wavelengths (to t10 nm) for the helium emission Emission 2 (nm) 450 470 490 500 510 530 590 670 Which wavelength(s) must be incorrect? Why The 670 nm wavelength must be incorrect since helium emission is not visible in wavelengths over 600 nm. The 500 nm wavelength must be incorrect since that is the wavelength at which black light is emitted The 510 and 530 nm wavelengths must be incorrect since they are not within the uncertainty range of any visible emission wavelengths for helium. The 450, 470, and 490 nm wavelengths must be incorrect since helium emission is not visible in wavelengths less than 500 nm. Which wavelength(s) has/have been missed? What is one possible reason for this? The 706 and 728 nm wavelengths have been missed. This is possibly because their emission wavelengths are so close to the infrared region. The 447 nm wavelength has been missed. This is possibly because the violet color is too dark to see in the spectrometer The 728 nm wavelength has been missed. This is possibly because it sometimes appears as a multi-colored band The 410 and 434 nm wavelengths have been missed. This is possibly because their emission wavelengths are so close to the ultraviolet region. Additional Materials Quantum States for the Visible Hydrogen Atomic Emission Spectrum
