How is the wavelength of a photon related to its energy, frequency and wavenumber? correct answer: Energy - As the wavelength is shorter, there is more energy and vice versa Frequency - The frequency of photon increase, causing the wavelength to go down and vice versa Wavenumber - Is reciprocal to the wave length (1/a) Why are energy levels descrete correct answer: Because each energy level has its own energy pathway. How to calculate the wavelengths of light from one energy level to ...
