Question: If the angle between the transmission axis of two polarizers is 90 degrees, what is the transmitted intensity of light?

Options:

Correct Answer: Zero intensity

Solution:

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

If the angle between the transmission axis of two polarizers is 90 degrees, what is the transmitted intensity of light?

If the angle between the transmission axis of two polarizers is 90 degrees, what is the transmitted intensity of light?

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: According to the properties of polarizers, when the angle is 90 degrees, the second polarizer blocks all the light that comes from the first polarizer.
Step 6: Therefore, no light is transmitted through the second polarizer, resulting in zero intensity of light.

Malus's Law – Malus's Law states that when polarized light passes through a polarizer, the transmitted intensity is proportional to the cosine square of the angle between the light's polarization direction and the polarizer's transmission axis.
Polarization of Light – Polarization refers to the orientation of the oscillations of light waves. Polarizers only allow light waves aligned with their transmission axis to pass through.
