Question

In the figure, unpolarized light with an intensity of 24.0 W/m2 is sent into a system of four polarizing sheets with polarizing directions at angles ?1 = 40.0?, ?2 = 19.0?, ?3 = 19.0?, and?4 = 32.0?, What is the intensity of the light that emerges from the system?

Question 2 Your answer is partially correct. Try again. In the figure, unpolarized light with an intensity of 24.0 W/m2 is sent into a system of four polarizing sheets with polarizing directions at angles 1-40.0, 2-19.0, 3-19. Oo, and 4 = 32.0°, what is the intensity of the light that emerges from the system? 102 esc Number-9544 0 units Number 8.09544 UnitsT W/ma2

Explanation / Answer

apply malus law as I = Io cos^2 theta

I = I0 *(1/2)*(cos^2(1+90-2))*(cos2(180-2-3))*(cos2(270-3-4))

I = Io * 0.5 * ( cos^( 40 + 90 - 19) * cos ^2(180 - 19-19) * cos^2(270-19-24)

I = Io * 0.5 *cos^(111) * cos^2(142) * cos^2( 227)

I = 24 * 0.5 * 0.128 * 0.621 * 0.465

I = 0.443 W/m^2
