Re: Light propagation orthagonal to vector - math help needed.

If we assume our sphere is a photonic wave hitting a flat surface it seems obvious that the reflected light on our surface rather rapidly expands as the photonic wave passes.

I would initially surmise that the orthagonal expansion would start from 'c' and reduce it's expansion rate immediately. In other words the reflection expansion rate is never at 'c' but always slowing from 'c', due to the nature of a sphere's impact point being impossible theoretically to measure.
But once contact has been made by our photonic wave the rate of expansion must start to slow from 'c'.

The thinking:
When measuring the speed of light are we measuring the leading point of the photonic wave or are we measuring later aspects of the wave? How does the energy from the wave propagate through absorbtion within our flat surface?
When measuring the velocity of light could we be measuing the reflections propagation rate and not the velocity of the photonic wave itself?
Could the time lag in waves impact across the flat surface be some how fundamental to what energy is regarding space and time.
When I first read this, I created the visual of a sphere with a plane slicing the sphere. The size of the
circle on the plane (that touches the sphere) is dependent on what percentage of the radius of the
sphere that is incident with the plane and normal to it. I never was able to create where 'c' was.
Note: from a point source light expands radially in all directions from that source. Whereas
photons are packetized light waves. This means their relative size is typically on the order
of yet can be significantly less than the wavelength of that light.
Reflected light travels at
the same speed of light in the same medium. Each photon goes in a specific direction and has a certain
energy (wavelength/frequency) and goes until it gets absorbed. The dual nature of light allows
anothe rmethod to describe the light as a wave whereby the sum total of light can be integrated
around the sphere in a contious fashion. Does this help.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
