Questions & Step-by-Step Solutions
What is the result of light passing through a polarizer followed by an analyzer oriented at 90 degrees to the polarizer?
Correct Answer: No light passes through
Step 1: Understand what a polarizer does. A polarizer allows only light waves that are aligned in a specific direction to pass through.
Step 2: Light that passes through the polarizer becomes polarized, meaning it vibrates in one direction.
Step 3: Now, consider the analyzer. The analyzer is another filter that can also polarize light, but it is oriented at a different angle.
Step 4: In this case, the analyzer is oriented at 90 degrees to the polarizer. This means it is perpendicular to the direction of the polarized light from the polarizer.
Step 5: Since the light is polarized in one direction and the analyzer is at 90 degrees, the analyzer will block all the light.
Step 6: Therefore, the result is that no light passes through the analyzer.
