Explain why this term is consistent with our view of the energy of electrons around a nucleus. 3) If the wavelength of green light is 380 nm, what is its frequency? How much energy is there in one photon of green light? What is the mass of one photon of green light? Note: ONE photon not one mole of photons! 4) If the frequency of blue light is 470 nm, what is its wavelength? What is the mass of one mole of blue light? 5) The human eye can detect a weak flash of light in which as little as 2.16x10-18J of energy strikes the eye. How many photons of light of wavelength 460 nm (blue light) must strike the eye in order to be seen? 6) What is the wavelength of Nolan Ryans fast ball if he throws it at 100.9 mph? A hardball weighs 5 oz. Note: 1 meter = 3.28 ft and 1 oz = 0.02835 kg. 7) Calculate the de Broglie wavelength of a particle whose mass is 1.0 gram traveling at a speed of 1.0 cm/sec. 8) Calculate the wavelength of the third line in the Lyman series. 9) Calculate the energy of transition for the second line of the Balmer series. What is the frequency of this transition? What is the mass of this photon of light? 10) How much energy does it take to move one electron from the ground state to the 6th excited state in a hydrogen atom? What is the frequency of this transition? What is the wavelength of this transition? What is the mass of the light used for this transition? 11) Please calculate the energy of transition to the 5th excited state in the Lyman series. The Rydberg constant = 2.18 x10-18 J. The sign on the energy of transition should be (positive or negative)? Please calculate the wavelength of the light during this transition. 12) Which of the following set of quantum numbers cannot exist? 2,1,0,+1/2 1,1,0,-1/2 6,3,-3,-1/2 7,0,0,+1/2 13) Write the quantum numbers for the following atoms.
