How can massless particles (photons) have momentum?
Interesting. Is this related to the wave-particle duality of light?
Yes, exactly. The wave-particle duality of light means that light can behave as both a wave and a particle. When it acts as a wave, it has energy and momentum. When it acts as a particle, it has no mass but does have momentum due to its energy and velocity.
