Answer:
Explanation:
The intensity of polarised light after polarization through angle θ
I = I₀ cos²θ
Here θ = 23 for first polariser
Intensity after first polarisation
= I₀ cos²23 = .846 I₀
For second polariser θ = 90 - 23 = 67 degree
Intensity after second polarisation
= .846 I₀ cos²67 = .13 I₀ .
