Calculate the wavelength of the lowest-energy line in the Lyman series to three significant figures. In what region of the electromagnetic spectrum does it occur? Given: lowest-energy orbit in the Lyman series. Asked for: wavelength of the lowest-energy Lyman line and corresponding region of the spectrum
bright, colored lines of hydrogen's visible spectrum. Each colored line corresponds to a particular wavelength of light. One of hydrogen's spectral lines is red light with a wavelength of 656 nanometers. Tubes filled with other gases produce different bright-line spectra that are characteristic of each kind of gas.
1. Determine the wavelength, frequency, and energy of the bright lines for the spectrum of several nonmetal, gaseous elements. 2. Use the activity data and observations to justify Bohr’s atomic model. Next Generation Science Standards* (NGSS) PE HS-PS4-1. Use mathematical representations to support a claim regarding relationships

A photon has an energy of 4.00 x 10–19J. Find... a. the frequency of the radiation. b. the wavelength of the radiation.
26 Ιουν 2023 · These lines are called spectra and correspond to fingerprint wavelengths (symbol for wavelength is \(\lambda\)) for a specific element. Figure \(\PageIndex{5}\) illustrates how the light from excited electrons can be diffracted to produce line spectra for the elements of hydrogen, helium, and iron.
Determine the wavelength, frequency, and energy of the bright lines for the spectrum of several nonmetal, gaseous elements. Use the activity data and observations to justify Bohr’s atomic model. Safety Procedures and Precautions. Spectral tubes get very hot. Have a hot glove or towel available for the removal of tubes from the power source.
You will calibrate your spectrometer using previously measured emission lines for mercury and helium and then use this calibration to determine the wavelengths of some hydrogen spectral lines.
