Polarization Rank the following according to the intensity of light that gets through, least to greatest i)unpolarized light through a polarizer set at 10 o to vertical ii)light polarized at 10 o to vertical through a vertical polarizer iii)light polarized at 10 o to vertical through a horizontal polarizer a)i, ii, iii b)ii, i, iii c)iii, i, ii d)all are equal

4. Polarization PAL Light from a laser is polarized at a direction 10 o clockwise from vertical. Draw this direction on the upper circle to the right. Label it “L” for laser light. This light will pass through a Polaroid, which has a polarizing direction that is 25 o counterclockwise from horizontal. Draw this polarizing direction also on the upper circle to the right. Label it “P” for Polaroid. a)Find the angle between the two directions you drew on the upper circle. 55 o b)Find the percent of the incident light that makes it through the Polaroid. 33% c)On the lower circle on the right, draw the direction of polarization of the light after passing through the Polaroid. vertical horizontal vertical horizontal
