An electron confined to an infinite potential well absorbs a photon with wavelength 𝜆. As a result, the electron makes a transition from the n = 1 state to the n = 7 state.What is the wavelength 𝜆' of the photon emitted when the electron makes a transition from the n = 4 state to the n = 1 state? (Give your answer as a decimal factor of 𝜆, eg write 2.5 if  𝜆'  = 2.5 𝜆)

The Rydberg-Ritz equation describes the wavelengths of photons absorbed or emitted when electrons in the hydrogen atom undergo transitions between a lower energy level, nl and an upper energy level nu.If nl = 2 and nu= 6, what is the wavelength of a photon that is absorbed or emitted when an electron undergoes a transition between these states?Express answer in nanometres, rounded to the nearest whole number.

A hydrogen atom initially in the ground level absorbs a photon,which excites it to the n = 4 level. Determine the wavelength andfrequency of photon.

A wavelength of 6.771 µm is observed in a hydrogen spectrum for a transition that ends in the nf = 7 level. What was ni for the initial level of the electron?
