As far as Einstein gravity is concerned, two EP are generally contemplated: the weak

equivalence principle (WEP) and the Einstein one (EEP).

We have considered the case for the impact of acceleration in special relativity and have derived an expression for the time dilation in an accelerated frame of reference, based on the

equivalence principle of general relativity.

Once the PEC current is solved, the scattering electric and magnetic currents can be computed using

equivalence principle as

Einstein's

Equivalence Principle requires that any two photons of different frequencies, emitted at the same time from the same source and traveling through the same gravitational fields, should arrive at Earth at exactly the same time.

It is to be noted that when the vector and scalar potential terms are equally important, the

equivalence principle can be represented by four scalar field components, two for the tangential components of [H.sub.1] and two for the tangential components of [E.sub.1].

equivalence principle," Progress In Electromagnetics Research M, Vol.

It is necessary to account for these implicit assumptions and use them--or similar assumptions--in developing an

equivalence principle. One assumption is that ventilation does, in fact, improve IAQ (i.e., that bringing in outdoor air has a net benefit of diluting indoor contaminants rather than a negative effect of bringing in outdoor pollutants).

Testing for the constancy of the fundamental constants has proven to be an efficient test of Einstein

equivalence principle that can be performed on astrophysical scales.

For example, Einstein's

equivalence principle was commonly mistaken (Cheng 2005), as shown in the British Encyclopedia, to be the same as the 1911 preliminary application of equivalence between acceleration and Newtonian gravity.

equivalence principle from lunar laser ranging, Phys.

Although physicists since Galileo knew this, Einstein was able to extract from this the

Equivalence Principle. This deceptively simple statement (that the laws of physics are indistinguishable locally in an accelerating or a gravitating frame) led Einstein to introduce a new symmetry to physics, general coordinate transformations.
