Can a wave rotate about its axis?? Can a transverse wave "rotate" about its longitudial axis (kind of like an airplane's "roll" maneuver)? If it could, i don't think we could detect it; if it did, i don't think anything will really get affected. But could it?? Not that it would...i mean, there's nothing making it rotate (or is there something??)...but could it? For example, when light diffracts in the air--well, it spreads, but could the wave itself "rotate" about its longitudinal axis (with all that spreading and diffracting)? not that it would affect anything, but could it??
