我想問下， x-ray等的EM wave, sound wave和 a radiation, B radiation, r ray 哪一個會deflected by magnetic field / by electric field?? why?? 還有是不是以上的除了sound都可以travel through vacuum??

x-ray等的EM wave, sound wave和 a radiation, B radiation, r ray 哪一個會deflected by magnetic field / by electric field?? why?? Only charged particles can be deflected by electric and magnetic fields. Among the items you mentioned, only alpha and beta are charged particles, and hence can be deflected by electric and magnetic fields. The other waves are not "charged", thus they will not be affected by the presence of electric or magnetic fields. 還有是不是以上的除了sound都可以travel through vacuum?? Yes, sound wave is a mechanical wave. Its propagation is achieved by the vibration of particles in the medium. Without such a medium, it is apparent that the wave cannot propagate through.
