Ells are constantly working to translate what they hear (english) into what they understand (their primary language). complicating this "double duty" is the fact that while working on the meaning of one sentence, they then completely miss the next thing the teacher says. for ells, then, how the teacher speaks is as important as what the teacher says.

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
