Answer:
Explanation:
Formula for intensity of light after transmission for unpolarised light is
I₀ / 2 , We shall take up 180 degree disk first .
For second transmission , the formula is
I = I₀ Cos²θ , θ is angle between axis of polarizer and axis of vibration.
If we take up 30 degree polariser
I = I₀ / 2 Cos²( 180 - 30 )
= .375 I₀
For third transmission
I_ final = .375 I₀ x cos( 90 - 30 )
= .1875 I₀
Final/I₀ = .1875
Did you mean acceleration? “Average acceleration is the final velocity minus the initial velocity per time taken”
