Unpolarized light of intensity 800 w/m2 is incident on two ideal polarizing sheets that are placed with their transmission axes perpendicular to each other. an additional polarizing sheet is then placed between the two, with its transmission axis oriented at 30∘ to that of the first. what is the intensity of the light passing through the stack of polarizing sheets? (express your answer to two significant figures.)

75 W/m²

Explanation:

= Unpolarized light intensity = 800 W/m²

= Angle between filters = 30°

Intensity of light after passing through first polarizer

Intensity of light after passing through second polarizer

Intensity of light after passing through third polarizer

The intensity of the light passing through the stack of polarizing sheets is 75 W/m²

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.
