  • #1
please let me know what is the nature of force that bends the path of photon during refraction.

There is no such thing as 'force' in modern, quantum-mechanics, approach.

In naive Newton's mechanistic model of light you may treat photon as a snooker ball, but not at the flat table, but rather on the one with one half lifted a bit comparing to other, so the photon receives impulse perpendicular to the refractive surface as crossing it.

There is no force involved in refraction it is caused purely by difference in the velocity of light in the two materials with different refractive indices.

Please note that the rules for classical waves also don't have a force altering the direction a wave propagates in. When the index of refraction changes bewteen two mediums the waves will have their path altered if they are entering the new medium at anything other than a 0 or 90 degree angle.
