What wavelenght is expected for light composed of photons

AI Thread Summary
The discussion centers on calculating the wavelength of light emitted during an electron transition from n=3 to n=1 in a hydrogen atom. Participants emphasize using the energy formula E=hc/λ, where E is the energy difference between the two states, h is Planck's constant, c is the speed of light, and λ is the wavelength. One user initially calculated a wavelength of 8.1 x 10^-6 m and sought confirmation of its accuracy. Others suggested checking textbooks and provided a link to HyperPhysics for additional resources on electron transitions, indicating that the necessary formulas and explanations are readily available in standard physics texts.

What wavelenght is expected for light composed of photons produced by an n= 3 to n=1 transition in a hydrogen atom?

How do u work this out? Iam pretty confused.

please help!
 
You should be able to find a formula for the energy of such transitions in your text, from the energy use E=hc/lamda to find the wavelength.
 
ok i did it and i got 8.1*10^-6 m.
Is that right? Thanxs.
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
