Sphere wave

WebSound waves are discussed in more detail in the next chapter, but in general, the farther you are from the speaker, the less intense the sound you hear. As a spherical wave moves out from a source, the surface area of the wave increases as the radius increases [latex] (A=4\pi {r}^{2}). [/latex] The intensity for a spherical wave is therefore WebBecause the surface area of a sphere is proportional to the square of its radius, the intensity of the wave is inversely proportional to the square of the radius. This geometric relation between the growing radius of a wave and …

WebThe photons within the EM waves are traveling in straight lines still. The "spherical" wave is just a bunch of regular EM waves combined together. That explains why the intensity diminishes the farther the radius from your source is. So instead of picturing waves as 3D, picture them as a bunch of 2D waves strung together.
