What you don't seem to follow is that if you are going to analyse the evolution of the wavefront using infinitesimal elements, you have to break the wavefront into an infinite number of such elements and then integrate over the whole set. > Tell me George, does that element show any tendency to shoot off in the > diagonal direction? The element doesn't move at all, it produces a contribution to the fields in the space around it and you integrate the contributions from all such elements to find the field at some new position.

I think you are being deliberately difficult. I think you are deliberately avoiding addressing what I am saying. If you deal with ONLY one point source then it disperses. If you shine a laser on a pinhole much smaller than the wavelengh, then diffraction at the edges gives you spherical waves emanating from the hole. In order to keep the narrow beam, you need a pinhole larger than the wavelength and you have to model the wavefront as a large number of small elements and integrate. > You know I am right.

In the laser frame that is correct, so your "infinitesimal elements" have to be aligned horizontally and you have to integrate over them. > According to you, a laser beam would disperse in all directions, in the source > frame. No, according to me, the wavefront from a point source (such as ONE infinitesimal element) would disperse in all directions in the ALL frames.

Nope, what comes out of a laser it is still light whether you move your hand or not.

No, what I am saying is that you can integrate over all the inifinitesimal elements to apply Maxwell's Equations (ME) and the result tells you the direction power will flow. If you start with a horizontal wavefront and apply ME then the wavefront will move vertically like this which is obviously wrong: > _ > _ > _ ^ > _ | > _ > > In all frames.

It is light in all frames. The beam is also vertical in all frames.

Let me remind you of what you said above: > The wavefront is horizontal. That horizontal line is merely a mathematical trick, it marks the highest field strength in a region but the field is actually a sine wave filling the volume of the beam. That propagating sine wave is what is called light (both fields of course but I'm keeping it simple here). > >> >Then you have to throw Maxwell's Equations in the bin. > >> >That was what was worrying them. > >> > >> Maxwell's equations apply to waves moving in one direction. > > > >Nope, they apply to the evolution of the fields whether there are > >waves involved or not and they apply in all frames.

No, according to Maxwell's Equations, the field from any single one of your "infinitesimal elements" would disperse in ALL frames. It is the interference between the infinite number of elements covering the horizontal surface of the wavefront that allows the beam to avoid dispersing. George

Don't be ridiculous, Henri. :-) What in a gas laSER do you think is Stimulated to Emit Radiation, if not the gas atoms? > Even if it were, the effect would be too small to worry about. Really, Henri? The light from a laser can go to the Moon and back, and still be coherent light. Do you think that could happen if the speeds of the photons were as different as the speeds of the atoms in the gas?

D = kw when dw/dt = 0 But D is caused by dw/dt, not w, because dD/dt <> 0 only when dw/dt <> 0. How incredible stupid! > The amount is virtually the same whether c or c+v is used. > Path length difference alone determines the position of the fringes. Small > variations in light speed do not make any significant difference to the result. How incredible stupid! The Sagnac effect IS "the small variations in light speed". delta_n = n+ - n- where n+ and n- are the number of wavelengths around the ring for the two beams, and delta_n is the difference. n+ = (S/lambda)(c+v)/c S = circumference of ring n- = (S/lambda)(c-v)/c delta_n = (S/lambda)2v/c S = 2*pi*r, A = pi*r^2, v = w*r, lambda = c/f, T = 1/f delta_n = f*4*pi*r^2*w/c^2 = f4Aw/c^2 delta_t = delta_n*T = delta_n/f = 4Aw/c^2 Seen this before? If this is the Sagnac effect, then it is caused by "the small variations in light speed". Paul |
