Chapter Five Extra Practice Problems 1. The yellow light given off by a sodium vapor lamp has a wavelength of 589 nm. What is the frequency of this radiation? 2. A laser used to weld detached retinas produces radiation with a frequency of 4.69 x 10 14 s -1 . What is the wavelength of this radiation? 3. Calculated the smallest increment of energy (that is, the quantum of energy) that an object can absorb from yellow light whose wavelength is 589 nm. 4. A laser that emits light energy in pulses of short duration has a frequency of 4.69 x 10 14 s -1 and deposits 1.3 x 10 -2 J of energy during each pulse. How many quanta of energy does each pulse deposit? (Hint: First calculate the energy of one quantum of this frequency.) 5. Calculate the wavelength of light that corresponds to the transition of the electron from the n = 4 to the n = 2 state of the hydrogen atom. Is the light absorbed or emitted by the atom? 6.
