Calculate the frequency, in hertz, of the photon that is emitted when a electron falls from level n = 10 to level n = 5 in the H atom.
Enter a numeric answer only, no units.
I tried asking in other places but ppl are so ambiguous about it.
:( please help me.
I used rydberg formula:
1/λ = RH ∙ (1/n₁² - 1/n₂²)
(RH rydberg constant for hydrogen, n₁ lower level, n₂ higher level)
Hence:
λ = 1/ [ 1.09678×10⁷m⁻¹ ∙ (1/5² - 1/10²) ] = 3.0392×10⁻⁶m
and then I converted to Hz = 9.89e14 but i still GOT IT wrong :( Please help me someone!
