Energy in transit

The wavelength of high energy transition of H atom is 91.2 nm Calculate the corresponding wavelength of He atom

A Rydberg atom is a single-electron atom with a large quantum number n. Rydberg states are close together in energy, so transitions between from a state n + 1 to a state n in hydrogen. The wavelength of the emitted photon varies with quantum number n as
