3. If you put 120 volts of electricity through a pickle, the pickle will smoke and start glowing orange-yellow. The light is emitted because sodium ions in the pickle become excited; their return to the ground state results in light emission. The wavelength of this emitted light is 589 nm. a) Calculate its frequency. Express your answer using three significant figures. b) Calculate the energy of the emitted light. Express your answer using three significant figures. c) What is the energy of 0.10 mol of these photons? Express your answer using two significant figures.
