    Answer:

    Explanation:

    Average intensity of incident light I₀ .

    intensity of transmitted light

    I = I₀ cos²θ

    if angle between transmission axis and angle of polarization of incident light be θ

    In the given case

    θ = 90 – angle the transmission axis makes with horizontal

    = 90- 30

    = 60°

    I = I₀ cos²θ

    = I₀ cos²60

    =   I₀ /  4
