The angle '$\theta$' between the transmission directions of polariser and analyser is varied, then the intensity 'I' of the light transmitted by analyser is correctly represented by
Answer & explanation
Correct answer: option 3
The correct answer is Option (3).
According to Malus's law -
$I=I_0\cos^2θ$
where,
I → Intensity of light
$I_0$ → Intensity of plane polarized light
θ → Angle between transmission axes of polarizer and analyses
