When light energy is emitted, Mass increases,: Einstein=E2=80=99s Sep.1905
derivation.
It is not consistent prediction from Einstein=E2=80=99s Sep 1905
derivation.
(written in response to comments)
How eq.(13) at page 201 in my paper I incorrect ? Then what is
correct equation?
In fact Eq.(13) in paper at page 201 is correct absolutely.
=E2=80=9D=E2=80=9D=E2=80=9D=E2=80=9DEq.(13) is based of Einstein=E2=80=99s=
Sep 1905 derivation ,
that THEORETICALLY when body emits Light Energy , the mass of body
INCREASE in some cases.=E2=80=9D=E2=80=9D=E2=80=9D=E2=80=9D=E2=80=9D=E2=80=
=9D=E2=80=9D
It is explained below in THREE SECTIONS.
Section A.
(i) Einstein has considered A body of mass 10gm (say), it emits two
waves under special conditions (two waves of equal energy L/2 each ,
emitted in opposite directions w.r.t measuring system) . Obviously
mass decreases, which is converted to light energy and Einstein=E2=80=98s
equation is
L =3Ddmc2
Energy emitted =3D decrease in mass .c2 (1)
(ii) If we consider the same body , it emits light energy at angle 90
w=2Er.t to the moving system , then again Einstein=E2=80=99s derivation gi=
ves
L =3Dmc2
Energy emitted =3D decrease in mass .c2 (2)
Both the cases are correct . Eq.(2) is not derived by Einstein.

(iii) If we consider the same body , it emits light energy at angle
90 o w.r.t to the moving system , then again Einstein=E2=80=99s derivation
gives
Ho =3D H1 + =CE=B2 L( 1 =E2=80=93 v/c cos89 o)
Ho =3D H1 + =CE=B2 L (1=E2=80=93 0.017452406 v/c)
Now proceeding as in Eq.(5) to Eq.(10) we get
=CE=94 m =3D =E2=80=93 0.03490L/cv + L/c2 (1=
3) at
page 201 of paper
Thus Einstein=E2=80=99s derivation implies that when body emits light energy
at angle 89 o then its MASS must INCREASE. If this angle is 0 then
Einstein=E2=80=99s derivation implies that when Light Energy is emitted ,
mass decreases.

roducts_id=3D4554
Thus Einstein=E2=80=99s derivation is not true in general, it holds good
under special conditions only.
I have given 2nd and 3rd example purposely that up to which extent
Einstein=E2=80=99s derivation depends upon angle. Angle up to 90 o is OK in
Einstein=E2=80=99s derivation of Sep 1905. If it slightly decreases (even
89.9 o ) then, then RESULTS ARE CONTRADICTORY to results.
Section B
It is crystal clear that as Einstein=E2=80=99s derivation as applicable to
first example ( two waves of equal energy L/2 each , emitted in
opposite directions w.r.t measuring system) and second example ( a
single wave of energy L emitted at 89 o or 89.5 o w.r.t measuring
system ).Thus Einstein=E2=80=99s derivation is also applicable to third
example (a single wave of energy L emitted at 89 o or 89.5 o w.r.t
measuring system).
As results are inconsistent then it is due to LIMITATIONS of
Einstein=E2=80=99s derivation only, as it is equally applicable in all the
three cases.
It is explained below that
law of =E2=80=98conservation of momentum=E2=80=99 holds good and =E2=80=98c=
onditions of
applicability=E2=80=99 of Einstein=E2=80=99s derivation are applicable to A=
LL THREE
CASES.
Part I
(a) Law of conservation of momentum is obeyed completely.
Conservation of momentum is meant for isolated system and
mathematically implies that
Initial Momentum =3D Final Momentum (3)
mu=3Dmv
As mass remains same in classical mechanics.
So u=3Dv
which is Newton=E2=80=99s First law of motion
It is used to calculate the velocity of recoil of body after emission
of energy in any way.
--It is applicable if body moves or remains at rest after emitting
energy.
Einstein has done the case when body remain at rest ONLY, I have
extended to it even if MOVES.
Take example of
-----Shot fired from gun, gun moves backward.
------ Light bullet fired from TOY Gun, system remains at rest.
Momentum is conserved in ALL THREE CASES and velocity of recoil is more
or less can be calculated using Law of conservation of momentum. This
is the use of law of conservation of linear momentum in this case.
As Einstein did all CALCULATION UNDER CLASSICAL CONDITIONS, hence net
REALTIVE velocity of body after recoil must be in classical region.
Again as Einstein did calculation under CLASSICAL CONDITIONS then
momentum variation has no effect on MASS.
Part II
Einstein=E2=80=99s derivation is applicable when body remains at REST or
MOVES.
The basis for this TRUTH lies in Einstein=E2=80=99s derivation. Purposely a=
nd
Especially eq.(1) shown below which is applicable for one or n waves.
(i) The central equation in Einstein=E2=80=98s equation is
l* =3D l{1 =E2=80=93 v/c cos =CF=86 } /=E2=88=9A[1 =E2=80=93 v2 /c2] =
(1) at page
196 of the paper.
This equation is from Einstein=E2=80=99s June 1905 paper AND Einstein used =
it
in derivation of L =3Dmc2.
With this equation magnitude of light energy is measured when one there
is relative velocity between light emitting body and measuring system.
Einstein considered two frames i.e. (x,y,z) at rest
(body placed in it) and second frame (X,Y,Z) moving with velocity v (
measuring system) .
Let body moves with velocity v=E2=80=99, then relative velocity will be
v+v=E2=80=99 and eq.(1) becomes
l* =3D l{1 =E2=80=93 (v+v=E2=80=99) /c cos =CF=86 } /=E2=88=9A[1 =E2=80=93=
(v+v=E2=80=99)2 /c2] (4)
So after emission of light energy, body remains at REST or MOVES,
eq.(1) [ at page 196 of paper ] is applicable.
When ever under any condition, body emits light energy, EINSTEIN=E2=80=99S
Sep. 1905 must give that MASS MUST DECREASE.
Thus out of three cases first one (two waves) , second one (for one
wave) interpretation for Einstein derivation is correct. How it
becomes incorrect for third case (one wave, with angle difference of 1
or less) becomes incorrect.
It is limitation of Einstein=E2=80=99s derivation.
Thus Einstein=E2=80=99s Sep 1905 derivation is correct UNDER SPECIAL
CONDITIONS not in GENERAL.
Explanation for eq.(16) in paper at page 202.
Consider two waves of energy 0.5001L
and 0.4999L , then apply law of conservation of momentum the velocity
of RECOIL can be calculated as
Vr =3D 1/10000000000000000000000000000000 =3D 10-^32 m/s.
Now v+v=E2=80=99 =3D v +10-^32
So eq.(1) is valid whether body is at REST or MOVES after emission
of light energy.
Einstein=E2=80=99s derivation of L =3Dmc2, the body may remain at REST or
MOVE, is applicable there is no rule of science which stops it.
Section 3
Part I
Thus it is concluded that Einstein=E2=80=99s derivation has four variables
(i) Number of light waves
(ii) Magnitude of energy of light waves
(iii) Angle at which light energy is emitted
(iv) Relative velocity v ( must be in classical region).
All these variables in Einstein=E2=80=99s Sep 1905 derivation have numerous
values. Energy may be emitted in any way, the mass of BODY DECREASES
experimentally ALWAYS.
But THEORETICALLY according to Einstein=E2=80=99s 29 Sep. 1905
derivation, in every time, result is not eq.(1) .
L =3Dmc2
Energy emitted =3D decrease in mass .c2 (1)
Einstein=E2=80=99s Sep. 1905 derivation also predicts MATHEMATICALLY that
when body emits Light Energy its mass must also INCREASE. It is not
true.
Hence Einstein=E2=80=99s derivation is true under special conditions only.
Part II
In addition after deriving
L=3D dmc2 (1)
Einstein simply replaced L and SPECULATED ( not derived)
E=3Ddmc2
where E is EVERY FORM OF ENERGY ( light energy, heat energy, sound
energy, chemical energy in form invisible radiation etc.). However
basis for derivation of eq.(1) is only for light energy eq.(1) at page
196 of my paper.
Thus we need to derive mass energy equation by other method and
generalized equation is
dE =3DAc2 dm
where A is coefficient of proportionality, like others in the existing
physics and its value depend upon experimental conditions.
