Relativity of Electro Magnetic Fields and Waves – Review and Clarification

The constancy of the speed of light, which is one of the two postulates of Special Relativity (SR) theory, is known to have a firm experimental and intuitive basis. However, SR requires length contraction time dilation hypothesis. In this paper, a new theory of light has been proposed as an alternative to this hypothesis. This paper proposes that light wave contracts towards or expands away from the source depending on the relative velocity (V) of the observer and the source so that the velocity of light in vacuum relative to any observer is always equal to C(3 x 10 8). The apparent velocity (C') of light relative to the source depends on the relative velocity (V) of the source and the observer so that the speed of light relative to an observer is always equal to C, i.e. C' - V = C (vector difference), in the reference frame of the source, and C' + V = C (vector sum), in the reference frame of the observer. Expansion or contraction of the wave is not a mere speculation but is a direct consequence of the principle of relativity and the well known phenomena of Doppler effect of light, in which speed of light remains constant and wavelength changes. The center of the spherical wave fronts moves at the velocity that the source had at the instant of emission, and yet the speed of light is the same constant C for any observer! According to SR , the center of a light wave front from a moving source is at the 'point in space where the source was' at the instant of emission. This is why SR doesn't predict stellar aberration in the reference frame of the earth. This assumption has to be investigated carefully with respect to the principle of relativity itself. The new theory agrees with the experimentally established fact that the speed of light is independent of the speed of the source (and the observer). It explains stellar aberration in both the earth and stellar reference frames. It predicts the null result of Michelson-Morley experiment. It agrees with Einstein's notion of motion, his two postulates and is in accordance with Galilean invariance principle. The Relativity of Electromagnetic Waves theory has been shown to better conform to the principle of relativity than Special Relativity does.
