Answer:
Only the frequency/wavelength is related to the energy in an electromagnetic (EM) wave.
Step-by-step explanation:
The energy of an EM wave is given by the relationship E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the EM wave. Frequency of an EM wave is related to its wavelenght by the formula c = fw, where c is the speed of light, f is the frequency, and w is the wavelength. So the energy of an em wave is directly proportional to it frequency, and inversely porportional to its wavelength. (The larger the wavelength, the lower the energy). Whil;e it may seem that amplitude should be related to the energy to an EM wave, the amplitude is more a measure of probability and is not connected to energy.
