Question

Use the information and images to answer the following question.A physics class is investigating the properties of light using polarizing filters. The students change the orientation of the two filters to see how much light can travel through both filters.To completely block the light, which orientation should the students use for the two filters?a)Filter A should be vertical and Filter B should be at a 60 degree angle.b) Filter A should be vertical and Filter B should be at a 45 degree angle.c) Filter A should be vertical and Filter B should be vertical.d) Filter A should be vertical and Filter B should be horizontal.

Answer 1

Assuming the filters are the same to completely block the light we need the fiters to be perpendicular ebetween each other, this comes from the fact that the first filter will only let light in a certan direction pass and the second one will filter ecxactly in the opposite direction and hence none of the light will be able to pass.

Therefore, the correct option is d
