Name: Flame Test Lab Prelab questions: Your instructor may ask you to answer these in your lab notebook in a "prelab" section. online or they may ask you to write your answers in your lab manual and submit them before starting your experiment. Follow your instructor's directions 1. Determine the frequency of photon of light that gives off 2.85 x 10-19 Joules. (Show all your work) so. The color would be orange/ red. 5hv (2.85 x/ 0J) - 16.626810**/s) v...

ATOMIC EMISSION SPECTROSCOPY ADVANCED STUDY ASSIGNMENT Name Section Date This assignment MUST be completed before the laboratory period begins. Wavelength values for the hydrogen emission spectrum are required for the experiment. A few answers have been provided for you. You may wish to verify some of these to ensure that your calculation methods and signifcant digits are correct. 1. Calculate energy values for the first SIX hydrogen energy levels usings En =-RH/n--(2.179 x10-18J/n2...

ATOMIC SPECTROSCOPY CALCULATIONS 1. Hydrogen Calculations a. Determine the wavelength for each peak observed in the hydrogen emission spectrum H Spectral Line Measured spectroscope value) 430 nm Line 1 Line 2 Line 3 Line 4 N/A b. Calculate the initial energy level of each transition observed in the H spectrum. For spectra in the visible region, nfinal is always 2. Be sure to show a sample calculation and...
assignment before beginning the laboratory experiment. Show all your work. 1. Describe or sketch a continuous emission spectrum. What produced this spectrum? (Solid or gas?), (hot or cold?) 2. Describe or sketch an emission-line spectrum. What produced this spectrum? (Solid or gas?). (hot or cold?) 3. The equation c = relates speed, wavelength, and frequency of EM (Electromagnetic) waves where c is the speed of light (C = 3.00 x 10 m/s). Use the equation to determine the frequency of...
Post-Laboratory Assignment 1. Which end of the spectrum shows higher energy transitions? (Circle one) blue end red end 2. As wavelength increases, energy increases decreases 3. As frequency increases, energy increases decreases 4. The intense Lyman-a hydrogen solar emission line at 121.58 nm is strongly absorbed by , in the stratosphere. This results in O dissociation and the ultimate formation of opone, O. to form the coone layer. a. Calculate the energy of one photon with a wavelength of 121.58...
3. Besides H, list other hydrogen like species in which the Rydberg constant in eq. 3 would still be 1.10 x 10"? 4. Is a Het 5-3 transition in the visible range? Calculate and explain. 5. Are there any electronic transitions of Het involving energy levels 1, 2 and 3 which are in the visible range? That is, will He emit any visible photons when the electrons fall from any level to levels 1, 2, and 3? If not, show...
