Revisit old topic - the speed of light
Keywords : light , magnetic permeability , dielectric constant , time, wave , space, inertial OF : Wu XingGuang（中国吴兴广） Light include : 1, and the vacuum permeability and dielectric constant , changes in the electromagnetic field caused by electromagnetic fields around the rate of change of C; 2, or medium for propagation of light in a vacuum , when the electromagnetic field each change there is no displacement . Every change in the speed of the electromagnetic field is zero. If a change in the electromagnetic field of each spatial movement that will have the speed , the speed of this time is the light propagation speed C with every change of the speed of the electromagnetic field vector . Light from the light propagation speed C of the electromagnetic field with each change in the speed of a joint decision . Properties of a relative motion field Substances produced field , such as an electronic field generated , magnetic field generated , will be with electrons or to movement of the magnet . Another scenario is that electronic or magnet do not exercise that electric and magnetic fields do not exercise, stationary reference frame motion , then the reference system seems to be moving electric and magnetic fields . We put the two movements have called relative motion , because both electromagnetic motion , or frame of reference moving , we say that the electromagnetic field of the electromagnetic field of movement is the movement of the reference system is poor, not the motion of an object with two objects the motion states. So from the substance of the field , whether the field has a relatively passive exercise it ? Passive electromagnetic field on such waves . Light on whether changes in the relative motion of the electromagnetic field it ? I think the change in the spatial movement of the electromagnetic field , with the relative motion . This is based on facts , here it comes soon . In this way, the movement is divided into two light , : 1 , light transmission ; 2 , the movement of the electromagnetic field changes . 2 changes in the electromagnetic field in the electromagnetic field itself exercise can 's movement in space , it can be the movement of reference , the reference line appears to be movement of the electromagnetic field . As described in the space reference system reference system is fixed in space , that space and spatial reference system that is mutually stationary motion says , then it seems that the electromagnetic field in the reference frame of reference described in the space of movement. 1, or that the movement of light waves propagate , is the speed of light C, the permeability and permittivity decision. We must distinguish between the two movements. Reference system or the movement of the observer changes can alter the movement of the electromagnetic field , electromagnetic field and the change of reference or the movement between the observer changed from rest into motion by which the speed becomes faster, but reference system or the viewer can not change the light propagation speed is the speed of light C. This creates a problem chasing light , when we chase the light speed of light , we will see what ? If we change the speed of light C as two sports fields , then we will arrive at this time do not see is the shock front of the electromagnetic field . In fact, this conclusion is wrong . Because, when the observer is not moving before you see is not the shock of the electromagnetic field . Electromagnetic field itself is not in front of the shock wave velocity waveform just move on electromagnetic waves and there is no forward movement. When we catch the light speed of light , I saw that in the space of stationary electromagnetic field , a constant electromagnetic field , while the speed of light in the opposite direction C Sport , continue to produce a constant ambient light , different electromagnetic fields . ( Eg observer away from the light , between the light source and the observer of light. ) Light sports include changes in electromagnetic wave propagation and movement , the speed of light is the speed of C and the electromagnetic wave velocity of closing speed . Since Maxwell predicted electromagnetic nature of light and the speed of the electromagnetic field after physicists thinking, this speed is relative to a reference line which says ? There is a particular frame of reference it? It is not. So the speed of light relative to C in the end Who said ? Binary phenomenon indicates that the movement of the light source has no effect on the speed of light . This is because the light source movement, the media is no movement , no change in the electromagnetic field along with light exercise . It seems the observer , electromagnetic fields and not forward movement ( later referred to the electromagnetic field does not move ) , the speed of light is the light wave propagation velocity C. Therefore, we conclude that the movement of the light source has no effect on the speed of light . Light source has no effect on the movement , this sentence is to say relative to the observer , then the light is it ? Appears in a wavelength in the observer , the light source appears , and the light source are mutually stationary space described , the light from the light source starting , the wavelength becomes shorter , according to the time is the amount of all of the moving object that is T = s1 / v1 = s2/v2 = s3/v3 = s4/v4 = ......, come to the same cycle , according to the velocity V = λ / T derived velocity of the change . Light toward the light propagation direction, the speed of light to the light source is smaller . Speed of light relative to the light source and the electromagnetic wave velocity is the speed of movement of the closing speed . Wavelength becomes shorter due to 1 ( the light source appears ) because of movement into the light fields 2 , the electromagnetic field has no effect on movement speed of light C , light is still C, and 1 and 2 co- movement is caused by the wavelength of light becomes shorter the velocity becomes smaller . At this point the velocity is the resultant velocity . Here the movement of the electromagnetic field or light velocity C has no effect . In the aberration phenomenon , the speed of light constant C , due to the Earth 's motion , the electromagnetic field of the earth appears to be moving toward the earth , so this time the movement is the propagation of light waves on the electromagnetic field of light moving toward the earth closing movement , in Earth seems that the light is not vertical but at an angle to shoot . Here, the relative motion of the electromagnetic field C has no effect on the speed of light . Pei search experiments, media campaign , resulting in changes in the speed of light . Seems to the observer , the light propagation medium in motion , the electromagnetic field of light on the spatial movement , the movement of the electromagnetic wave caused by the movement of the closing movement of the closing speed of light changes , it appears that the speed of light in the viewer . If the light line with the principle of relativity , then the light in different inertial same speed , so that the movement of the media come to no effect on the speed of light , medium light propagation in motion when the light changes in the electromagnetic field on the move together with the media they need each other still , that the media is completely driven by the movement of light on the electromagnetic field changes with the movement . In this case, changes in the electromagnetic field exercise on C does not affect the speed of light . So Pei search experiments, media should also be entirely driven by the movement of the light on the changes in the electromagnetic field with the movement. Lightspeed C by the permeability and permittivity decision , then the speed of light relative to the C Who said it ? Through the above , we know that C is the speed of light with respect to changes in said electromagnetic field . Light on the relative changes in the electromagnetic field of light speed is always a C, and changes of the electromagnetic field is independent of the movement , has nothing to do with the speed of change in the electromagnetic field . That is the speed of light C unchanged, but the variable speed of light together . In any inertial mechanical laws are the same , the same laws of electromagnetism , for example, Maxwell's equations , Coulomb force , in any inertial frame are the same. Observed in different reference frames , the movement of the object may be different , for example, in a reference frame is stationary object in another frame of reference see , it may be in motion, in a different frame of reference in their speed and direction of movement may be different ; Similarly , the speed of light in different inertial system is the same , but in a light propagating inertial reference frame appears in another closing speed of light may fluctuate .
