Asked by Jake

Green light is emitted when electrons in a substance make a particular energy-level transition. If blue light were instead emitted from the same substance, would it correspond to a greater or lesser change of energy in the atom? and why?

Answers

Answered by Elena
λ (green)≈ 550 nm,
λ (blue) ≈ 450 nm.
λ (green) > λ (blue)
The energy of emitted photon is
ε =h•c/ λ =>
ε(green) < ε(blue).
If blue light was emitted, it corresponds
to a greater change of energy in the atom.
