Answer:
vertical, at an angle between horizontal and vertical, horizontal.
Explanation:
The vertically polarized light will be able to pass completely through the vertical filter, since it blocks all waves except those that travel in the vertical direction. Â
If the polarizing filter at an angle between horizontal and vertical, is placed between the vertical and horizontal polarizers, a certain percentage of the incident light polarized vertically will be transmitted, being polarized with a direction according to the angle of said filter.
Therefore, after exiting this filter, the light will be able to transmit after crossing the horizontal filter
