Photons are massless so in order to avoid the term m we can use debroglie's dual nature theory or whatever you just said

If you can check, I can send an image on how they derived it.

Here we require the change in momentum to find the force and then the pressure, and since we can't associate mass to photons, mass energy equivalence can be used to replace mass (p.s. It was explained in photoelectric effect to find out radiation pressure)I don't remember the exact source, I...

Which one? I believe speed of light is constant in every frame we presume. I found it in a book.

Even if a beam of light strikes a reflective surface at an angle 'A', the change in momentum should be 2mc, P=2IcosA/C but I find it P= 2Icos^2(A)/C.
