Light is incident on a polarizer analyser combination with 37o between their axes. The percent of incident light transmitted is:
well, thru the first plate, 50 percent gets thru (the light in alignment with the polarizer). In the second plate, 50*cosine37 now gets thru.
To find the percent of incident light transmitted, we need to use Malus' Law for the intensity of polarized light passing through a polarizer:
I = I₀ * cos²θ
Where:
- I is the intensity of the transmitted light
- I₀ is the initial intensity of incident light
- θ is the angle between the transmission axes of the polarizer and the analyzer
In this case, the angle θ is given as 37 degrees.
To calculate the percent of light transmitted, we need to find the ratio of the transmitted intensity (I) to the incident intensity (I₀) and multiply by 100.
First, we calculate the intensity transmitted through the polarizer-analyzer combination:
I = I₀ * cos²37°
Then we calculate the percent of transmitted light:
Percent Transmitted = (I / I₀) * 100
Let's plug in the values and calculate it.
