Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who discovered Polarization (waves)?1808
2. What is the discoverer?Étienne-Louis Malus
3. What is the primary polarization mechanisms?Selective absorption (filters), reflection, scattering, birefringence
4. What is polarization of light?Polarization is when light waves vibrate in only one direction instead of many random directions. It helps us see things clearer and makes some glasses work.
5. How can we make light polarized?We can use polarizing filters that absorb waves that vibrate sideways, or we can reflect light at a special angle, or we can scatter light in the sky, or we can put light through special crystals that split it.

Transverse Wave: A wave where the oscillation is perpendicular to the direction of energy transfer.
Brewster's Angle: The specific angle at which light reflecting off a surface becomes completely polarized.
Birefringence: The optical property of a material having a refractive index that depends on the polarization and propagation direction of light.
