Wavelength and Frequency Video Lessons

Concept: The Electromagnetic Spectrum

# Problem: If you put 120 volts of electricity through a pickle, the pickle will smoke and start glowing an orange-yellow color. The light is emitted because the sodium ions in the pickle become excited; their return to the ground state results in light emission (see Figure 6.13b and Sample Exercise 6.3). (a) The wavelength of this emitted light is 589 nrn. Calculate its frequency.
