If you apply it to a ray, the term 'mass' (in connection to rays) would be meaningless. If you look only at the sample, the term 'energy' is not well defined, since a sample is 'stuff'. And material objects have mass. But you cannot really say 'stuff has energy', since to measure energy would require a process, in which energy is released. That would be a radioactive decay, of course, but the term energy would be used for the emitted rays and not for the mass of the material object. And if you apply the correct relations, the equation 'E=m*c²' is wrong, since the signs are wrong. TH
