Momentum of all photons , p=mc. There is no question of different momenta for two photons, is there? They only differ in freq n wavelength.

No, pawan, all photons don`t have same momenta as according to De Broglie relationship, momentum is plank`s const. divided by wave length...both the statements are true.

Gotcha Momentum is a vector quantity. Like two photons having same wavelength but travel in opposite direction have opposite signs for momenta

(a) is false as two photons with same wavelength will have same magnitude of momentum but there mometa might be different. (b) is true.
