suppose an atom absorbs a single photon and then gives back the energy of that photon in two successive transition. one transition produces a photon of 400nm, and the second transition produces a photon of 200nm. what is the wavelength in nm, of the original photon?

A ground state hydrogen atom absorbs a photon of light having a wavelength of 93.03 nm. it then gives off a photon having a wavelength of 2165 nm. What is the final state of the hydrogen atom?
An atom (not a hydrogen atom) absorbs a photon whose associated wavelength is 234 nm and immediately emits a photon whose associated wavelength is 550 nm. How much net energy is absorbed by the atom in this process?
A ground state hydrogen atom absorbs a photon of light having a wavelength of 92.27 nm. It then gives off a photon having a wavelength of 383.4 nm. What is the final state of the hydrogen atom? Values for physical constants can be found here. Number
A hydrogen atom is in the ground state. It absorbs energy and makes a transition to the n = 5 excited state. The atom returns to the ground state by emitting FOUR photons ONLY. What is the wavelength of the second highest energy photon? (answer in m)
A ground state hydrogen atom absorbs a photon of light having a wavelength of 92.57 nm. It then gives off a photon having a wavelength of 1944 nm. What is the final state of the hydrogen atom? Values for physical constants can be found in the Chempendix. Cni 2canned with Eam Scanner
A singly ionized helium atom is in the ground state. It absorbs energy and makes a transition to the n = 6 excited state. The ion returns to the ground state by emitting FIVE photons ONLY. What is the wavelength of the second-highest energy photon?
