i understand thankyou so much for helping me out sir!

We know that light is an electromagnetic wave and it does interact with charges. It contains magnetic field and electric field oscillating perpendicularly but when we apply an electric or magnetic field in any direction to the wave the applied electric field or magnetic field vector doesn't alter the magnetic or electric field in the electro magnetic wave (according to vector addition rule)....why? I essentially want to know if its possible to "hold" light in a 3 demensional view, that has also a ceilling to stop the light from projecting it further (what maybe will be achieved by destroying it on a particular point) Hope i explained and gave a detailed question because i can't find any answer to get from in my college books. And the internet failed me a couple times on this subject
