If a polarizing filter reduces the intensity of polarized light to of its original value, what is the ratio of the amplitude of the electric and magnetic fields in the light incident from and emergent from the filter?
The angle between the axes of two polarizing filters is . By how much does the second filter reduce the intensity of the light coming through the first?
Two polarizing sheets are placed together to form a combination with transmission axes of the polarizers oriented at an angle to each other. With the polarizers so aligned, the amount of light that passes through the sheets is of the maximum possible intensity of plane polarized light that the combination can transmit. What percentage of unpolarized light would be transmitted through the combination?
What angle would the axis of a polarizing filter need to make with the direction of polarized light of intensity 1.00 kW/m2 to reduce the intensity to 10.0 W/m2 ?
The light incident on polarizing sheet is linearly polarized at an angle of with respect to the transmission axis of . Sheet is placed so that its axis is parallel to the polarization axis of the incident light.
What fraction of the incident light passes through ?
What fraction of the incident light is passed by the combination?
is rotated so as to produce a maximum value of intensity transmitted by the combination. What is the ratio of the maximum transmitted intensity to the transmitted intensity before was rotated?
