Abstract |
In his paper Einstein derived ∆L=∆mc2 (light energy mass equation). It has not been completely studied; it is only valid under special conditions of the parameters involved e.g. number of light waves, magnitude of light energy, angles at which waves are emitted and relative velocity v. Einstein considered just two light waves of equal energy, emitted in opposite directions and the relative velocity v uniform. There are numerous possibilities for the parameters which were not considered in Einsteins derivation. ∆E=∆mc2 is obtained from ∆L=∆mc2 by simply replacing L by E (all energy) without derivation. Fadner correctly pointed out that Einstein neither mentioned E or ∆E=∆mc2 in the derivation. Herein additional results are critically analysed, taking all possible variables into account. Under some valid conditions of parameters ∆L=∆mc2 is not obtained e.g. sometimes the result is Ma =Mb or no equation is derivable. If all values of valid parameters are taken into account then the same derivation also gives L ∆mc2 or L =A ∆mc2, where A is a coefficient of proportionality. Thus Einsteins derivation under valid parameters also predicts that energy emitted may be less than or more than ∆L=∆mc2. |
