Displace the mass to the side by about 30 degrees and let the mass swing. The mass moves from one extreme point, through the center, to the extreme point on the other side and then back to the starting point. Watch the repetitive pattern and figure out what you would define as one cycle. (There is more than one configuration that can be considered a cycle.)

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.
