9. Quantum Mechanics / The Energy of Light / Problem 2

The dipole in an O–H polar covalent bond is a very important property of water and accounts for most of its characteristics. An O–H covalent bond requires 464 kJ/mol to break. Since this is a high-energy bond, only a wavelength of radiation within the ultraviolet region has enough energy to break this bond. Calculate the longest wavelength of radiation with enough energy to break this covalent bond.
