I had question jehaan sir but could not ask ask due to some technical issue. sir you said that gamma rays do not have any mass says but sir according to the e=mc^2 formula it has a mass. i am not saying the light particles (photons) them self have mass i am saying that the energy in the photons has mass
Hi Shreya,
Yes you are partially right about Einstein’s equation for E=mc^2. This formula which is widely known is a special case where the particles/object is at rest and has no momentum. The general/complete formula is E^2 = p^2c^2 + m^2c^4. Since photons are massless, for all photons, this formula becomes E^2 = p^2c^2. This means that the photon gets all its energy from momentum(p).
There is an interesting additional effect contained in the general equation. If a particle has no mass and is at rest (p = 0), then the total energy is zero. But an object with zero energy and zero mass is nothing at all. Therefore, if an object with no mass is to physically exist, it can never be at rest.
I hope this answers your question.
Feel free to write to us if you have any further doubts.
