Have a question related to this quote from Wikipedia:
"The amplitude of a spherical wave will fall off as the inverse square of the distance from the source."
Is it correct to think that the energy of the whole of the wave is maintained but that it's the disbursement of the wave which results in a reduction in amplitude rather than it actually "losing steam", so-to-speak? Also, is its speed maintained over the course of its travels? Thanks.
