Homework Statement
Diagram not to scale:
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Energy (J)
n = 3 ----------------------------------------… - 0.24x10^-16
n = 2 ----------------------------------------… - 0.54x10^-18
n = 1 ----------------------------------------… - 2.18x10^-18
In which level is the electron to be found in a normal hydrogen atom? (need help with this question)
If the electron is promoted to the second excited state, (n=3), calculate the wavelengths of the photons which may be emitted?
(Planck's constant, h - 6.6x10^-34 Js c = 3.0x10^8 ms^-1)
Any help is greatly appreciated
Homework Equations
ΔE = hf
λ = c/v
h = 6.6x10^-34
c = 3.0x10^8
The Attempt at a Solution
n = 2 = - 0.54x10^-18
n = 3 = - 0.24x10^-16
ΔE = - 2.54x10^-17
ΔE = hf = - 2.54x10^-17 = 6.6x10^-34f
f = - 2.54x10^-17/6.6x10^-34 = -3.71x10^16 Hz
λ = c/v
λ = 3.0x10^8/- 3.71x10^16
λ = - 8.09x10^-9
See I know it's wrong as I end up with a negative value
Could you please point me in the right direction and explain the steps that are wrong please
