What are the frequency and wave length of a photon emitted during a transition from the n=5 state to n=2 state in the hydrogen atom?

What is the wavelength of a photon emitted during a transition from n = 5 state to the n = 2 state in the hydrogen atom

What are the frequency of a photon emitted during a transition from n = 5 state to the n = 2 state in the hydrogen atom?

What is the wavelength of a photon emitted during a transition form the n_(i) = 5 state to the n_(f) = 2 state in the H atom?

Calculate the energy of the hydrogen atom in the states n = 4 and n = 2. Determine the frequency and wavelength of the emitted radiation in a transition from n = 4 to n=2 state. Is this radiation visible?
