so first your going to use v=Δd/Δt given you the answer 80 i think that's right
The light transmitted by a filter is <em>less bright </em>than the light that hits it.
A filter only absorbs/removes part of the light that hits it. That means it removes some energy from the incident light. The remaining light carries less energy, so it must be less bright.

You have to have electrons that are in the materials conduction band. Then you apply a voltage across the material.
Answer:
It will emerge at its initial speed not a slower speed.
Explanation:
It will emerge at the initial speed because the medium at the point of emergence is the same as the medium before incidence.
Light moves at a constant speed in any particular medium. Hence, the speed of light in air is constant in air and the speed of light in glass is constant in glass.
