I need some help with these problems I am completely stumped can someone walk me through how to do these? I’m not asking for you to do them for me I just want to know how to do them, or where to start.
Wavelength 632 nm , I found the frequency to be 4.75 *10^14 sec , and the energy of a photon of this electromagnetic radiation to be 3.15*10^-19 J. It then asks for the energy of one mole of photons of this radiation? I am completely stuck on how to find that.
2) What is the energy found in the n=4 level of a hydrogen atom? Is the electron in this atom in ground state?
I am used to work with problems that say when it jumps from level such to level such but on this I am stuck. Also the En is confusing me…
3)The electron transitions where an electron falls from a Bohr orbit having a value n>4 to the n=4 orbit gives rise to a series called Brackett series. Calculate the wavelength of the lowest enegy electromagnetic radiation given off in this series of lines. What is the wavelength of the highest energy line in the Brackette series?
Give: triE=-2.1788*10^-18 J[1n/f^2-1n/i^2]
I am completey stumped on this one.
I spent all night trying to figure these out and scanning through my notes and book but am completely lost. Any help will be highly appreciated! This is due today also so really need some help. Again since it’s an assignment I have to do it I only need some guidance to this not answers.
