- Find the wavelength (in nm) of the fourth line in the Lyman series. (Round your answer to at least one decimal place.) Identify the type of EM radiation.arrow_forwardHow fast should an electron move such that its kinetic energy is equal to the energy of a red photon (λ = 722 nm). For simplicity, express your answer as v x 105 m/s and type in just the value of v. Use three significant figures in your answer.arrow_forwardIf a hydrogen atom in the ground state absorbs a 93.7 nm photon, corresponding to a transition line in the Lyman series, how does this affect the atom's energy and size? How much energy is needed to ionize the atom when it is in this excited state? Give your answers in absolute units, and relative to the ground state. (the Lyman series is a hydrogen spectral series of transitions and resulting ultraviolet emission lines of the hydrogen atom as an electron goes from n ≥ 2 to n = 1 (where n is the principal quantum number), the lowest energy level of the electron.)arrow_forward

Be sure to show all units and write clearly. Does your answer make sense? How do you know? Thank youarrow_forwardLet's think more about de Broglie's relation. Macro scale matters have wave nature, i.e., wavelength? (1) Our (humans) movements also have wavelength? Calculate wavelength of a human with a speed of 1 m/s.
