Explain a wavelength of 925.4 nm has been detected from the emission of a hydrogen gas tube while under excitation from a high voltage source in a lab. This was caused by an electron dropping from a higher voltage source. This was caused by an electron dropping from a higher energy level to the N= 3 level. Find out the energy level number of the higher level
