Multiple-choice questions may continue on the next column or page find all choices before answering. Atomic Theory 1 Electromagnetic Radiation calculations. Plancks constant. Energy of a photon. Particle-in-a-box calculations. H-atom spec- trum and the Rydberg equation. Remember the Rydberg constant, R , can have various values - make sure you convert appropriately. Wave functions and the corresponding quan- tum numbers. 001 10.0 points What is the correct order of decreasing fre- quency? 1. ultraviolet radiatioin, visible light, in- frared radiation, radio waves 2. radio waves, infrared radiation, visible light, ultraviolet radiation 3. infrared radiation, radio waves, visible light, ultraviolet radiation 4. visible light, ultraviolet radiation, in- frared radiation, radio waves 5. radio waves, visible light, ultraviolet radi- ation, infrared radiation 002 (part 1 of 2) 10.0 points Light with a frequency of 6 . 91 10 14 Hz lies in the violet region of the visible spectrum. What is the wavelength of this frequency of light? Answer in units of nm. 003 (part 2 of 2) 10.0 points When an electron beam strikes a block of copper, x-rays of frequency 2 . 74 10 19 Hz are emitted. What is the wavelength of theseare emitted....
