Why don't light particles become heavier as they travel t the speed of light?

ScientificBoysClub · « **on:** 30/04/2009 09:41:26 »

Light particles travel with C; then why those particles won't get heavier ?

BTW what is the difference between light particles and and Proton particles ?

Well light is form of photon particles which is small packets of energy called Quanta !! ..... If other particles travel with velocity of light they get Heavier .....

than why not Energy particles get heaver ?

so, my conclusion is Energy can't be manipulated. Only mass can be !!

but Energy is in the form of particles they should get heavier ....... ??

The answer for photon is :-
http://en.wikipedia.org/wiki/Photon
I don't agree that light can gain weight..
How can you say that energy can't be manupulated..It can be manupulated.. some times mass can keep same.. There is no doubt that both can be change...
What is the relationship b/w light,energy & mass, gravity...

I think there will be some reasons..

I mean manipulation of Energy among the particles of light !!........ it must be always constant .. so, we can't change it !!

Energy can't be manupulate into light particle....It's not possible

But light it self energy ...... and it comes from mass E=mc^2

yeah live example ...

Burn a paper mass converts it self in to energy ...
Light from an electric Bulb ... Electric Bulb uses flow of electrons and converts mass of electrons into light ......
Light is a form of energy that can be released by an atom. It is made up of many small particle-like packets that have energy and momentum but no mass. These particles, called light photons, are the most basic units of light.

Atoms release light photons when their electrons become excited. then you know that electrons are the negatively charged particles that move around an atom's nucleus (which has a net positive charge). An atom's electrons have different levels of energy, depending on several factors, including their speed and distance from the nucleus. Electrons of different energy levels occupy different orbitals. Generally speaking, electrons with greater energy move in orbitals farther away from the nucleus. When an atom gains or loses energy, the change is expressed by the movement of electrons. When something passes energy on to an atom, an electron may be temporarily boosted to a higher orbital (farther away from the nucleus). The electron only holds this position for a tiny fraction of a second; almost immediately, it is drawn back toward the nucleus, to its original orbital. As it returns to its original orbital, the electron releases the extra energy in the form of a photon, in some cases a light photon.

The wavelength of the emitted light (which determines its color) depends on how much energy is released, which depends on the particular position of the electron. Consequently, different sorts of atoms will release different sorts of light photons. In other words, the color of the light is determined by what kind of atom is excited.

This is the basic mechanism at work in nearly all light sources. The main difference between these sources is the process of exciting the atoms.

Then also to do this work you need some energy,
What are you saying
Energy = Light with C-constant..

Question please... Confused

Man E=MC^2 is very easy to understand .....

1.now take 111 grams of Uranium
2. Excite it using fusion (it causes chain reaction)
3. than M=111 grams of mass and u need to multiply with atomic Mass
4. than multiply C^2 (squared )
5. than u will get amount of heat Energy of uranium explosion .... with units of joules Lise Meitner discovered it ... she was first women to apply Einsteins equation in chemistry and copied by chemist Otto Hahn
Now ,
M = 111 grams to o.111kg
C= 300,000,000
E= ?
E= MC^2

E = 0.111 x 300,000,000 x 300,000,000
= 10,000,000,000,000,000 Joules of Energy released

so , from small amount of mass we can get large amount of energy .....!!!

nothing much but the thing is when a mass travels with some velocity it gets heavier due to Momentum ...
even light particles have momentum... why not heavy ?

They have no mass.

I know but ...... ?? well they should get something (some property )

all moving things should gain some momentum ??

They have no mass.

if we apply energy on mass ... that energy gets converted to momentum or gets heavier .. when particle it self is energy ?? energy supplied to it ... something should happen ?? what is it ?

Light is a type of electromagnetic fields... where it is has effect but no mass

yeah but still unknown stuff is there in light ......

like unsolved question ....... Light is a wave or particle ?

Raghavendra · « **Reply #16 on:** 30/04/2009 11:36:07 »

it has wave particle nature...
E=mc^2
and
E=hν

hv=mc^2

m= hv/c^2

taking square on both side

m^2 = √hv/c....

v= c/λ

yeah Planck said that light is in the form of particle in nature ....
