Homework Statement
Plane polarised is incident normally on a polerizer which can rotate in plane perpendicular to light. The intensity of of incident light is 8W[m][/-2] and transmitted intensity is 2W[m][/-2] if polerizer is rotated 90 deg what is the new transmitted intensity
Homework Equations
The Attempt at a Solution
Root of (8 squared minus 2 squared)=root 60
Resolving vectors?
Answer was 6W[m][/-2]
Which is just eight minus two, help? I don't know why
