. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Energy (J)

n = 3 ----------------------------------------… - 0.24x10^-16

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

2. Relevant equations

ΔE = hf

λ = c/v

h = 6.6x10^-34

c = 3.0x10^8

3. 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
