Best ResponseYou've already chosen the best response.0The energy of an EM wave is expressed as\[E = {hc \over \lambda}\] and the wavelenght, \(\lambda\), is expressed as\[\lambda = {c \over f}\]Therefore, \[E = hc\]where \(h\) is Plank's constant, \(c\) is the speed of light, and \(f\) is frequency in Hz

Best ResponseYou've already chosen the best response.0Whoops\[E = hf\] not E=hc We can observe that there is a direct relationship between frequency and energy.
