Q: If the angle between the transmission axis of two polarizers is 90 degrees, what is the intensity of light passing through them?

Solution: When the angle between the transmission axes of two polarizers is 90 degrees, no light passes through, resulting in zero intensity.

Steps: 6

Step 1: Understand what a polarizer is. A polarizer is a device that allows light waves of a certain orientation to pass through while blocking others.
Step 2: Know that each polarizer has a transmission axis, which is the direction in which it allows light to pass.
Step 3: When two polarizers are placed one after the other, the angle between their transmission axes affects how much light can pass through.
Step 4: If the angle between the transmission axes of the two polarizers is 90 degrees, it means they are perpendicular to each other.
Step 5: When the polarizers are at 90 degrees, the first polarizer allows light through, but the second polarizer blocks all of it because it is oriented to block the light coming from the first.
Step 6: Therefore, the intensity of light that passes through both polarizers is zero.
