I want to understand the concept of polarization of light. I would like someone to clarify how I am thinking about it:
If light is a transverse wave and it is basically an electric field(E) and magnetic field(B) each oscillating in different directions (axes) which are perpendicular to each other say x-axis for E and z-axis for B and the light propagates in the y-axis. Polarization means that that light is filtered by blocking all light except the one traveling in a certain direction.
1) Say for example, that only light that is traveling vertically is allowed, this means that all light traveling horizontally is blocked. Is this right?
2) If light traveling vertically is allowed only, what does this mean for the Electric Field and Magnetic Field. Is one of them blocked? I know that it doesn't make sense to me, because light is made out of both of E and B. Is it the case that when talk about polarization of light then we are talking about the wave itself which means the E and B fields are inside the wave and their directions of oscillation are actual vertical or horizontal directions?
