Does photons experience friction as they r having particle nature also?

i am in confusion myself. it has something to do with the refraction of light. in Richard feynmann's quantum electro dynamics he talks about slowing up of light in a lens.

photons do have mass-E=mc^2
therefore
m=c^2/E

Photons are energy packets released by a source of light they are particle in nature and as they are emitted with velocity hv
Where h=plank's constant
v=frequency

Iam back !
No. friction is basically electromagnetic force in reality. Remember there are only 4 fundamental forces in nature.
photons are chargeless and massless.

well the scientist in me says that as the velocity of photons is very high and their mass is negligible,
they experience no friction

no photons does not experience friction. they are mass less.

No
They exist as a particle and wave at the same time. When they interact with matter they seem to behave more like waves.
Friction no but they can be deflected by atoms, so not slowed down but they do interact.

They are supposed to be massless, hence the question of friction does not arise

They don't seem to as their speed is always the same (namely, that of light in whatever medium they are travelling through) and they don't lose any energy after travelling many billions of light-years.
