Can a photon be deflected by an electric field ? By a magnetic field ?

Can an electromagnetic wave be deflected by an electric field? By a magnetic field ?

A beam of protons is deflected sideways. Could this deflection be caused (1) By an electric field ? (2) By a magnetic field ? (3) If either could be responsible how would you be able to tell which was present ?

Which of the following particle can be deflected by electric and magnetic field?

Induced electric field due to changing magnetic field

Photons are not deflected in electric and magnetic field as they are

When beryllium is bombarded with alpha-"particles" , extremely penetrating radiations which cannot be deflected by electrical or magnetic field are given out. These are

Assertion: X-rays cannot be deflected by electric or magnetic fields . Reason: These are electromagnetic waves.

Assertion (A),If electrons travel undefeccted by the electric field E and magnetic field B then the velocity of electrons is given by V=e/b . Reason (R ) : When both electric and magnetic field are applied simultaneously on electron beam. If force due to electric field is equal and opposite to force due to magnetic field then they travel undeflected.
