Intensity of Electromagnetic Waves as a Function of Frequency, Source Distance and Aperture Angle

By Raul Fattore

Intensity of Electromagnetic Waves as a function of frequency is usually not treated by the scientific community.

The energy transport in Electromagnetic Waves (EMW) calculated by means of the Poynting vector formula, might not yield to correct results, because it only gives an average energy on a surface. There is no reference about the volumetric energy distribution at a distance from the source, nor to the frequency of the EMW.

How can the intensity of EMW be written in terms of frequency and distance to the source?

How to calculate the volumetric energy of EMW?

How does the intensity change with the aperture angle (solid angle of a cone in space) from the source?

How to relate intensity with frequency, area, and aperture angle in one equation?

How to obtain the wave equation of the interference caused by slit diffraction to compute the Intensity?

In this study, you'll find the answers to the questions above and learn that the result obtained here agrees to the famous Planck equation (E=h f ). Moreover, a wave equation for the interference pattern produced by slit diffraction is obtained, but calculation of pattern intensities is left for you with the given formulas.

There is no special physics field of my choice. Whenever I need to find answers to some questions that I cannot find anywhere, it is an opportunity to exercise my "Brainuter" trying to obtain the answer by developing a scientific approach. I am particularly interested in the study of negative mass, gravitational control, inertial control, gravitational interaction, static and dynamic deformation of celestial bodies, the impact of the mass of the universe on celestial bodies, atomic theory, the atom model, particle physics, wave-matter interaction, cosmology, and electrodynamics. I do not meet the requirements to publish my studies in reputable scientific journals because I am an independent scientist and do not work for any universities or research institutions. This is why I created my own website, physics-answers.com, to provide answers about how Mother Nature works and to spread the word about my research. I have a university degree in Electronics Engineering from the Buenos Aires National University of Technology (Universidad Tecnologica Nacional, U.T.N., FRBA) and have specialized in Automatic Control Systems, Computer Science, Electro-Biomedical, and Industrial Electronics. Besides loving travel, I’m also passionate about Physics.

Abstract

Intensity of Electromagnetic Waves as a function of frequency is usually not treated by the scientific community.

The energy transport in Electromagnetic Waves (EMW) calculated by means of the Poynting vector formula, might not yield to correct results, because it only gives an average energy on a surface. There is no reference about the volumetric energy distribution at a distance from the source, nor to the frequency of the EMW.

How can the intensity of EMW be written in terms of frequency and distance to the source?

How to calculate the volumetric energy of EMW?

How does the intensity change with the aperture angle (solid angle of a cone in space) from the source?

How to relate intensity with frequency, area, and aperture angle in one equation?

How to obtain the wave equation of the interference caused by slit diffraction to compute the Intensity?

In this study, you’ll find the answers to the questions above and learn that the result obtained here agrees to the famous Planck equation ( ). Moreover, a wave equation for the interference pattern produced by slit diffraction is
