1. An electron initially moves in first excited state, if it absorb energy with frequency 5x10" Hz. Find the momentum of this electron before and after interaction with photon energy. 2. An electron initially moving in the third orbit around the nucleus of the hydrogen atom. Find the photo energy which emitted from electron transition to the first excited orbit (using Rydberg formula). Calculate the De-Broglie wavelength of the electron in the orbit before transition. 3. Determine the De Broglie wavelength for electron moving in the third excited orbit around the nucleus of the hydrogen atom.
