Question

we associate energy and linear momentum with electromagnetic waves is angular momentum present also? ​

Answer 1

Explanation:

Linear momentum is mass multiplied by velocity, so it follows that angular momentum is the moment of inertia, measured in kilogram meters squared, multiplied by angular velocity, measured in radians per second. Radians are just an alternative to degrees.

Light, or more generally an electromagnetic wave, carries not only energy but also momentum, which is a characteristic property of all objects in translational motion. ... These two rotations are associated with two forms of angular momentum, namely SAM and OAM.

Hope this answer helps you....
