Two beams,

A

and

B

, of plane polarized light with mutually perpendicular planes of polarization are seen through a polaroid. From the position when the beam

A

has maximum intensity (and beam

B

has zero intensity), a rotation of polaroid through

30 °

makes the two beams appear equally bright. If the initial intensities of the two beams are

I_{A}

and

I_{B}

respectively, then

\frac{I_{A}}{I_{B}}

equals:
