Thanks Dale, PAllen, Ibix. The QM is beyond me at the moment

Just to confirm the parameters of the question - a perfectly mirrored box (massless or massive), stationary with respect to the viewer, containing a single photon. Does the resistance to acceleration (mass) vary as the photon is a) being reflected by the side and b) traveling between the sides

A massive box would be acceptable - the important part is the single photon and the finite time between collisions/reflections

Poorly phrased but here goes - I'm trying to understand some of the SpaceTime videos on youtube, specifically the massless mirrored box and how the mass (ie resistance to acceleration) is a function of the change in momentum of the contained (constrained) photons. It makes sense but raises a...
