Hi I have a question is about the photon. How could a photon has momentum, when its mass equal 0 kg? Because momentum is p=mv right? and if the mass is 0, the velocity should be 0 too right?
For a given wavelength, and knowing Planck's constant and the velocity of light in a vacuum, the mass of a photon can be calculated using the de Broglie wavelength equation. If photon mass = 0 then the de Broglie wavelength is undefined because dividing by 0 is undefined. IMO quantum mechanics is a mess for many reasons.
Einstein's equation: E=mc^2 doesnt work for massless objects or moving objects. This is the full or more general equation: E^2 = (pc)^2 + (mc^2)^2 For a photon, since m=0, it reduces to E =pc. Hence p(momentum) = E/c. So photons, though they have no mass, have momentum. This applies to EM waves as well where we measure momentum density. Using E=hv where v is frequency (quantization of energy) p = hv/c = h/(wavelength) which is the debroglie wavelength Correct me.if I'm wrong

😢😢😢Hello, sir. I have a question. How can a photon have fixed frequency? We know that Photon is a quanta or packet of energy and It means Photon is localised and a localised particle don't have fixed frequency. It have superposition of all possible frequencies. according to quantum physics 🙏🙏🙏🙏🙏 please answer me

Hi I have a question is about the photon. How could a photon has momentum, when its mass equal 0 kg? Because momentum is p=mv right? and if the mass is 0, the velocity should be 0 too right?
Because newtonian mechanics dont work on quantum scale. Thats the entire point of quantum mechanics:)
For a given wavelength, and knowing Planck's constant and the velocity of light in a vacuum, the mass of a photon can be calculated using the de Broglie wavelength equation. If photon mass = 0 then the de Broglie wavelength is undefined because dividing by 0 is undefined. IMO quantum mechanics is a mess for many reasons.
In quantum mechanics momentum=energy/velocity
And photons are the packets of energy so they have both energy and velocity
Einstein's equation: E=mc^2 doesnt work for massless objects or moving objects. This is the full or more general equation:
E^2 = (pc)^2 + (mc^2)^2
For a photon, since m=0, it reduces to E =pc. Hence p(momentum) = E/c.
So photons, though they have no mass, have momentum. This applies to EM waves as well where we measure momentum density.
Using E=hv where v is frequency (quantization of energy)
p = hv/c = h/(wavelength) which is the debroglie wavelength
Correct me.if I'm wrong
