Question

Electron A falls from energy level X to energy level Y and releases blue light. Electron B falls from energy level Y to energy level Z and releases red light. Which transition, from X to Y or from Y to Z, has a greater energy difference? Explain your answer and how you arrived at it.

Answer 1

E = hf, and h is the Planck's constant. When larger frequency is needed, more energy will also be needed. Since the blue light has the higher frequency, it would be the level X to Y's transition which is the one that has the highest energy difference.
