A hydrogen atom in one of its excited states ha an energy of -1.5129^20 J.
What is the frequency of radiation is emitted when the atom relaxes down to its ground state?
Would you look at your post and proof it please. That 10^20? Is that right?
a hydrogen atom in one of its excited states has an energy of -1.5129x10^-20 J
The energy of the H atom in its ground state is -2.18E-18. Find the difference in the energy, change the negative sign to a positive sign then E = hf and solve for f = frequency. Is that something like 10^15 Hz? You should confirm that.
To determine the frequency of radiation emitted when the atom relaxes from its excited state to its ground state, you need to use the equation:
E = h * f
where:
E is the energy difference between the two states (in joules),
h is Planck's constant (6.626 x 10^-34 J·s),
and f is the frequency of the radiation emitted (in Hz or s^-1).
First, let's calculate the energy difference between the excited state and the ground state:
ΔE = -1.5129 x 10^20 J
Now, rearranging the equation to solve for frequency:
f = ΔE / h
Substituting the values:
f = (-1.5129 x 10^20 J) / (6.626 x 10^-34 J·s)
Calculating this, we find:
f ≈ -2.284 x 10^53 Hz
However, negative frequencies are not meaningful in this context. So, the correct frequency, considering only the magnitude, would be:
f ≈ 2.284 x 10^53 Hz
