Question

2. Two polarizers are oriented at42o to each other and a polarized light is incidenton them. If only 22 percent of the light gets through both of them,what is the angle between the initial polarization direction of theincident light and the first polarizer? degrees

Explanation / Answer

if the intial intensity is I0 throughthe sheets then we have from malus law I1 = I0 cos21 I2 = I1 cos22       = I0 cos21 cos2 2 0.22 I0 = I0 cos21 cos2 420 solve for 1 =--------0 solve for 1 =--------0
