An incident electromagnetic wave is polarized and its e vector has a maximum value of 6 volts/m. it is incident on a polarizer whose transmission axis is rotated at an angle of 45 with respect to the incident e vector. what is the maximum value of the transmitted e vector?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
