1.7 Exercise 1

Avg difficulty 2.5

Although we did not specify the direction in the example, let’s say the polarizing filter was rotated clockwise by 71.6°71.6 ° to reduce the light intensity by 90.0%90.0 \%. What would be the intensity reduction if the polarizing filter were rotated counterclockwise by 71.6°71.6 °?
