1. In this section you were told that light with greater frequency has greater energy. a. Which color in the visible spectrum of hydrogen has the greatest energy? The least energy?

The question is asking about the energy of light in the visible spectrum of hydrogen. The visible spectrum of light is the portion of the electromagnetic spectrum that is visible to the human eye. It ranges from red to violet. The energy of light is directly proportional to its frequency, and frequency is inversely proportional to wavelength. Therefore, light with a shorter wavelength has a higher frequency and thus higher energy. In the visible spectrum, violet light has the shortest wavelength and therefore the highest energy, while red light has the longest wavelength and therefore the lowest energy.
