The energy of a photo is related to its frequency and its wavelength. Calculating frequency from wavelength For this the formula to use is f V l where f refers to the frequency V refers to the waves velocity and l refers to the waves wavelength. Substitute the numerical values of the above into the wavelength equation.
This is the currently selected item.
Convert the wavelength into meters if necessary. It is directly proportional to frequency and inversely proportional to wavelength. Convert the wavelength into meters if necessary. Wave energy from graphs.
