Lesson Worksheet: Polarization of Light Physics • 9th Grade

Unpolarized light traveling in air that has a refractive index of 1 reflects from a film of oil. The angle from the normal to the surface of the oil of reflected light that is completely polarized is . What is the refractive index of the oil? Give your answer to one decimal place.

Unpolarized light passes through two polarizers that have polarization axes apart from each other. The intensity of the light after it passes through both polarizers is 0.15 W/m². What is the initial intensity of the light?

Unpolarized light passes through two polarizers. The light has an initial intensity of 1.8 W/m². The intensity of the light after it passes through both polarizers is 0.85 W/m². What is the angle between the polarization axes of the polarizers?

Vertically polarized light with an intensity of 1.25 W/m² passes through a polarizer aligned at an angle , above the horizontal, as shown in the diagram. What is the intensity of the light transmitted through the polarizer? Give your answer to two decimal places.
