 | What is polarization of light? |  Card: 1 / 30 |
| Restricting light vibrations to a preferred direction from all possible directions. | Card: 2 / 30 |
| True or False: Longitudinal waves can be polarized like transverse waves. | Card: 3 / 30 |
| False. Only transverse waves can be polarized because longitudinal disturbance is along propagation direction. | Card: 4 / 30 |
| In plane polarized light, electric vector vibrates in _____ direction(s). | Card: 5 / 30 |
| One fixed | Card: 6 / 30 |
| Which method produces polarized light by selective absorption? | Card: 7 / 30 |
| C) Tourmaline crystals | Card: 8 / 30 |
| What angle do reflected and refracted rays make at Brewster's angle? | Card: 9 / 30 |
| 90 degrees (perpendicular to each other) | Card: 10 / 30 |
| If unpolarized light intensity is 100 units, what intensity emerges from polarizer? | Card: 11 / 30 |
| 50 units (half the incident intensity) | Card: 12 / 30 |
| According to Malus's law, transmitted intensity formula is I = I₀ _____ | Card: 13 / 30 |
| Cos²θ | Card: 14 / 30 |

| True. The cement helps separate ordinary and extraordinary rays through internal reflection. | Card: 16 / 30 |
| What is μ equal to at Brewster's angle iₚ? | Card: 17 / 30 |
| Tan iₚ (tangent of polarizing angle) | Card: 18 / 30 |
| In birefringent crystals, how many rays does unpolarized light split into? | Card: 19 / 30 |
| B) Two | Card: 20 / 30 |
| Why does skylight appear polarized when scattered at 90°? | Card: 21 / 30 |
| Rayleigh scattering partially polarizes light perpendicular to scattering direction. | Card: 22 / 30 |
| What happens when polarizer and analyzer axes are crossed (90°)? | Card: 23 / 30 |
| Zero transmitted intensity (complete extinction of light) | Card: 24 / 30 |
| Dichroism is the property where crystals absorb _____ polarized component more strongly. | Card: 25 / 30 |
| One | Card: 26 / 30 |
| Polaroid sunglasses reduce glare by blocking light polarized from which surfaces? | Card: 27 / 30 |
| C) Flat surfaces | Card: 28 / 30 |
| If analyzer makes 60° with incident polarized light, what fraction transmits? | Card: 29 / 30 |
| ¼ (cos²60° = ¼) | Card: 30 / 30 |
