Polarization

What is the function of a polarizer?

• To block all light completely

• To change the color of light

• To allow only light vibrating in one direction to pass through

• To reflect light in all directions

What is an analyzer in a polarization setup?

• A light source

• A detector that blocks all light

• A second polarizer used to detect the direction of polarization

• A mirror that redirects light

What type of light does a polarizer act on?

• Infrared light only

• Polarized light only

• Unpolarized light

• Reflected light only

What happens to the light intensity when the analyzer is rotated to 90° relative to the polarizer?

• All light passes

• Half the light passes

• No light passes

• Light becomes brighter

At what angle between polarizer and analyzer does half the light pass through?

• 0°

• 45°

• 60°

• 90°

What mathematical law describes how light intensity changes with the angle between polarizer and analyzer?

• Newton's Law

• Malus's Law

• Ohm's Law

• Hooke's Law

When the polarizer and analyzer are aligned (0° angle), what is the result?

• No light passes

• 25% of light passes

• 50% of light passes

• All polarized light passes
