Properties of light

[CraigD]

A small asteroid hits the ocean about hundred meters away from you and causes a one meter wave that starts propagating toward you. When the wave hits all you will detect is a very small piece of the total energy output of that asteroid impact. The production of light is very similar to this scenario.

There are a several of problems applying this by analogy to light.

 

One is that the energy per unit length of a circular water wave follows an inverse distance law ([math]\frac{E}{l} \sim \frac{E_0}{l r}[/math]). The energy per unit area of a many-photon light source follows an inverse square distance law ([math]\frac{E}{l^2} \sim \frac{E_0}{l^2 r^2}[/math]).

It is impossible to produce a single photon.

This is simply untrue.

 

Like many if not all physics students, as an undergrad, in reproducing the double slit experiment, I made a single photon source simply using an ordinary monochrome lamp and smoked glass filters.

 

Due the their usefulness in quantum cryptography, automatic single photon sources are now available commercially – see New Products / QCV - Quantum Computing Victoria

It hasn’t, in an absolute sense, gone anywhere.

 

Consider the difference between being bumped on a ski slope by someone skiing beside you, vs. being slammed into the same skier while you’re standing still. Clearly, the same skier, moving at the same speed relative to the surface of the ski slope, has different kinetic energies when colliding with you at different relative speeds.

 

By analogy, light is similar.

 

This analogy doesn't stand up as the photon has the same speed wheather it is red shifted or not! and.. not all the skiers energy is obsorbed by the other skier, but the photon is!

 

Bosons – which include photons – don’t interact with one another. They do interact with fermions, which include electrons.

 

Technically, this lack of interaction is described by Bose–Einstein statistics

 

Yes.

 

This surprising experimental result, conventionally known as the double slit, or Young’s, experiment, is one of the cornerstones of modern physics.

 

I've carried out this experiment(previously) with a laser beam but not with individual photons. The resulting interference pattern was explained to me as, the wave like properties of light, constructively and destructively interacting with each other. This can''t be the case as bosons don't interact! The pattern has to be explained as the re-direction of the photons by the grating. This is why I asked about the single photon.

Craig, you claim you have created a single photon. I claim you allow one cycle ( a piece of the total output) to pass through your device and call it a photon. Pointing to my strange claims post which should be viewed as a truth if the viewee weren't tied up in the importance of their own vast knowledge, is valid since it describes the logical production of a photon as evidenced by Larmor radiation unless you can provide a better explanation.
