Multiple-choice questions may continue on the next column or page find all choices before answering. The due time is Central time. Brodbelt CH301 Practice Exam 1 Photon Comparison1 08:02, general, multiple choice, < 1 min, fixed. 001 A visible light photon has a than a photon of microwave radiation. 1. higher frequency 2. lower speed 3. longer wavelength 4. greater speed 5. lower energy Msci 05 0905 08:02, general, multiple choice, > 1 min, fixed. 002 The higher the energy of electromagnetic ra- diation, the 1. shorter its wavelength. 2. longer its wavelength. 3. greater its mass. 4. lower its frequency. 5. higher the velocity of light. Msci 02 1258 08:02, general, multiple choice, > 1 min, fixed. 003 The photoelectric effect confirms that 1. photons can be converted to electrons, thus proving the dual particle/wave nature of photons. 2. photons can generate electrical fields, showing that photons carry charge. 3. photons of certain energies can be ab- sorbed by atoms, thus showing that electons exist in energy levels that are specific for each element. 4. photons cause the gain or loss of electrons in atoms, thus proving that elements have different isotopic forms. 5. electrons can be converted to photons by absorption of x-rays, thus proving that electrons carry discrete amounts of energy. Photon Energy 01 08:05, general, multiple choice, < 1 min, fixed. 004 What is the energy of a photon emitted from an electron in a hydrogen atom when it jumps from the n = 7 to the n = 3 level? 1. 7 . 9093 10- 20 J 2. 4 . 1524 10- 19 J 3. 1 . 97728 10- 19 J 4. 2 . 1800 10- 20 J Brodbelt 05 04 08:07, general, multiple choice, > 1 min, fixed. 005 An electron in a 3 d orbital could have which of the following quantum numbers? 1. n = 3; = 2; m = 0 2. n = 3; = 1; m =- 1 3. n = 3; = 2; m =- 3 4. n = 3; = 0; m = 0 5. n = 2; = 2; m = 2 Create assignment, 54700, Practice 1, Sep 12 at 11:16 am 2 6. n = 2;...
