Homework Statement Using the uncertainty principle find the energy required for the electron to be confined inside the hydrogen atom. Use the radius of the atom 1 x 10-10 m for Δr. Express your answer in eV, rounded up to the nearest hundredth. Homework Equations ΔxΔp\geqh/4pie...

o ok. and for the momentum. would i just use mass and velocity of an electron?

Homework Statement Using the uncertainty principle find the energy required for the electron to be confined inside the hydrogen atom. Use the radius of the atom 1 x 10^-10 m for Δr. Express your answer in eV, rounded up to the nearest hundredth. Homework Equations Δx(Δp)\geqh/4pie x=...

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

electron volts. so we find n first right

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? Homework Equations 1/lambda= 1.97x10^7(1/1^2-1/k^2) The Attempt at a Solution...

ok so if its off by .08 to being a integer it won't absorb?? and you said that energy of photon has to be equal to transition energy to absorb... but isn't it always equal?? because photon= hc/lambda, but energy transition= the same thing. so doesn't this say that it ALWAYS absorbs because it...

wait. nm i did it the other way anyways R(1/1^1-1/n^2) i did the formula like this up there to get n=1
