After passing through a polariser a linearly polarised light of intensity I is incident on an analyser making an angle of 30∘30^\circ with that of the polariser. The intensity of light emitted from the analyser will be 2I3\frac{2I}{3} I2\frac{I}{2} I3\frac{I}{3} 3I4\frac{3I}{4}

Multiple Choice Options

  • A 2I3{{2I} \over 3} 3 2 I _
  • B I2{I \over 2} 2 I _
  • C I3{I \over 3} 3 I _
  • D 3I4{{3I} \over 4} 4 3 I _

Step-by-Step Verified Solution

According to Malu's Law I o u t = I i n cos 2 _ I o u t = I cos 2 ( 30 _ ) I o u t = 3 I 4
