Answer to Question 1

Red light has a longer wavelength than violet light; therefore a red photon contains less energy than a violet one. Since the photon given off when an electron's energy level changes has an energy equal to the energy difference between the two levels, the less energetic photon represents a smaller difference.

Answer to Question 2

D
