What is the effect of polarization when two polarized sheets are overlaid and rotated?

• They change color

• They reduce light passing through to darkness

• They increase transparency

• They produce a 3D effect

How does light typically travel according to the electromagnetic wave model?

• With only magnetic waves visible

• With both electrical and magnetic components

• With only electrical waves visible

• In a straight line without any wave components

What causes the polarization effect when light reflects off surfaces like water?

• The light waves align perpendicularly to the direction of travel

• The light changes color

• The light waves scatter randomly

• The light speeds up

What does the term 'polarity' refer to in the context of light waves?

• The intensity of the light

• The direction of the electrical component of the wave

• The color of the light

• The speed of the light wave

How do polarized sunglasses help you see underwater?

• By changing the color of water

• By reducing surface glare

• By magnifying underwater objects

• By increasing the amount of light

Why can you see through glass even though light is absorbed and not actually passing through?

• Because glass amplifies light

• Because glass changes the light's color

• Because atoms in the glass re-emit the absorbed light

• Because glass only absorbs ultraviolet light

What role do the molecules in polarized materials play?

• They change the color of light passing through

• They limit vibration, affecting how light is absorbed or transmitted

• They block all light waves

• They vibrate to generate heat
