Consider the following arrangement of 4 polarizers. The first has a horizontal transmission axis, the second is oriented at 30 degrees with respect to the horizontal, the third at 60 degrees to the horizontal, and the fourth at 90 degrees to the horizontal. The light incident on the first polarizer from the left is unpolarized with intensity Io=1000 W/m . a)What is the final intensity of the transmitted light? b)If the third and fourth polarizers are interchanged, the final intensity of the transmitted light will 1. increase 2. remain the same 3. decrease c)Start with the original situation shown above. If the first polarizer is replaced with a quarter-wave plate, the final intensity of the transmitted light

The light incident on the first polarizer from the left is unpolarized with intensity Io=1000 W/m .
a)What is the final intensity of the transmitted light?
b)If the third and fourth polarizers are interchanged, the final intensity of the transmitted light will
1. increase
2. remain the same
3. decrease
c)Start with the original situation shown above. If the first polarizer is replaced with a quarter-wave plate, the final intensity of the transmitted light will be:
1. Larger by a factor of 2
2. Smaller by a factor of 1/2
3. Larger by a factor of 1/cos 2(30 degrees)
4. Smaller by a factor of cos2(30 degrees)
5. The same as in the original situation
