so the photon as linear momentum(P=E/c),spin(intrinsic angular momentum),and now we find out it has orbital angular momentum. Is there any other momenta associated with a photon?
P.S.
What does intrinsic mean anyway?

Where are you guys getting the idea that we didn't know that light has orbital angular momentum?

Instrinsic means that it is a fundmanetal property of the photon, i.e. all photons have a spin quantum number(s) of 1 which is related to the spin angular momentum by:
√s(s+1)h/2π
As far as I'm aware, there are no other sorts of angular momentum other than those described associated with the photon (excpet for things like total angualr momentum which is the sum of spin and orbital angular momentum).
does not seem to have any assymmetry that would decide the direction of twist. What then determines whether the helical wavefront is right or left handed?
If we calculate the interference pattern generated by combining LG00 and LG0+1...
Orbital angular momentum is a physical quantity that describes the rotation of an object around a fixed point, also known as its center of rotation.
Orbital angular momentum is measured by multiplying the mass of an object by its velocity and its distance from the center of rotation.
Orbital angular momentum is an important concept in physics as it helps explain the motion of objects in circular or elliptical orbits, such as planets around the sun.
Yes, orbital angular momentum can be changed by altering the mass, velocity, or distance of an object from its center of rotation.
Orbital angular momentum has several real-world applications, such as in satellite communication, planetary motion, and quantum mechanics.
