Unformatted text preview: Consequently, the transmitted intensity is I = fI cos 2 θ + 1 2 (1 − f ) I . As the Flter is rotated, cos 2 θ varies from a minimum of 0 to a maximum of 1, so the transmitted intensity varies from a minimum of I min = 1 2 (1 − f ) I to a maximum of I max = fI + 1 2 (1 − f ) I = 1 2 (1 + f ) I . The ratio of I max to I min is I max I min = 1 + f 1 − f . Setting the ratio equal to 5 . 0 and solving for f , we get f = 0 . 67....
