Question

When you move a rope up and down, waves are created. If the waves pass through a slot, they will be affected differently, depending on the orientation of the slot. Using the rope waves and the slot as a model, explain how polarizing glasses affect light waves.'

a. If the wave (electric field) is vertical and slit (polarizing molecules in the glass is horizontal), the wave will pass.

b. If the wave is vertical and slit is vertical, the wave will not pass.

c. If the wave is horizontal and slit is horizontal, the wave will pass.

d. If the wave is horizontal and slit is horizontal, the wave will not pass.

I think it is A, but I am not sure.

Answer 1

Option (C) is correct option. If the wave (electric field) is horizontal and the slt is horizontal the wave will pass.

  

If wave makes an angle " € " with the slit then only the component of wave along slit passes through the slit. We call we have a polarized light.
