Re: silly inverse square law question.


Excellent ... then you should be fully cognizant of how ISL is the spherical dissemination pattern of energy in particle packets (i.e. photons) from a PLS and that a PLS / ISL is an even distribution pattern based upon diffusion / path of least resistance / until acted upon by another object. Photons are particles of energy. Photons have a mass and are matter (really tiny matter, but matter nonetheless). They follow the laws of Conservation of Energy. Those particles continue until they are acted upon by another object. The subsequent path & energy of the photons after interaction with another object continue iaw with AI=AR as predicated by the object it interacts with ... most notably, the angle of incidence, and index of refraction (relative to opaque, transluscent, transparent) and the energy absorption into the body, rendering the remaining amount of energy to be determinant in the color of the light reflected.

Is there anything there that is objectionable to your understanding of physics of light as taught by Oxford?

Newton's First Law of Motion states that a body at rest will remain at rest unless an outside force acts on it, and a body in motion at a constant velocity will remain in motion in a straight line unless acted upon by an outside force.

Light travels at a constant speed and direction (definition of velocity) in a given medium (i.e. air, vs. water, vs. vacuum, etc.) IAW Newtons' First Law of Motion. In other words, it doesn't slow down or change direction, except when acted upon by another object (outside force). When a photon comes into contact with an object, the interaction / exchange of energy properties, (i.e. color, direction, etc.) occurs. Then, when the photon continues on its new path, it will continue to again travel iaw with Newton's First Law of Motion ... which is STRAIGHT LINE iaw with AI=AR.

Curious80's indication that light travels iaw ISL after interacting with another object / outside force is in direct violation of Newton's First Law of Motion.
