Election x falls from engery level a to engery level b and releases blue light. Elsctron y falls from energy level an to engery c and releases red light. Which transition, form A to B or from B to C, has a greater energy difference? Explain your answer and how you arrived at it

Answer

From A to B

Explanation

from the spectrum of visible light ,the production red light has the lowest energy difference as the wavelength is shorter and frequency lower

on the other hand, blue light is produced when the energy difference is higher.

0.11 m/s and 0.28 m/s should be correct
