alright.
so i solved for n and i got 1.08 and since only integers are accepted i would round off to 1 right?
and since k=1 and n=1 how do i know whether it is absorbing or not?
and how could i solve with the other equation? once i found the energy of the photon what would i do after?
o ok. well the energy of the photon would be hc/lambda which would be 2.1 eV nm but why do we need this?
i thought that you could just find n by putting in lambda and k (fundamental state) on the 1/lambda=1/k^2-1/n^2 and solving for n
ok appreciate your help. here's the question
A photon with λ = 600 nm interacts with a hydrogen atom in fundamental state. Will the photon be absorbed? Justify your answer.
and btw I am homeschooled and I am taking the ut austin high school program, and we don't get textbooks but its an online...
Homework Statement
ok so i know whenever a photon is absorbed it will jump up a energy level and when it is emmited it releases energy. but my question is, for example, if k=1 (fundamental state) in a hydrogen atom and they give you the given wavelength of the photon, you solve it and you...
o ok.
but if k=1 and i get n=1.08 and since only integers are accepted would it round off to 1 and not absorb? or since it is a larger number than 1 it would absorb?
btw
if it absorbs, would the rest of the energy that was left that didnt absorb turn into kinetic energy?
Homework Statement
how can i tell if a photon is being emmited or absorbed?
Homework Equations
hc/lambda= energy per photon
1/lambda=r(1/n^2-1/k^2)
The Attempt at a Solution
photons are absorbed when the energy of the photon= energy of transition?
when are they emmited?
and i...
o ok.
stupid me i see what i did now.
and btw
how do you know when a photon is absorbing energy?
is it when the photon energy is the same to the energy transition? but I am kind of confused because i thought they were always equal to each other
o ok. so this wouldn't absorb, because if n is equal to 1 it still wouldn't absorb because the energy of transition would not be equal to energy of the photon right?
hf= 2.1
energy of transition (if n=1) i= 0
and a number like 1.08 could not be used only integers right?
so that is why is no...
Homework Statement
The wavelength of the photon emitted when a hydrogen atom undergoes a transition from the k state to the n = 1 state is around 94.8 nm. How much is k?
