What is the phenomenon of the bending of light when it passes from one medium to another called?

  1. Refraction

  2. Reflection

  3. Dispersion

  4. Polarization


Correct Option: A
Explanation:

Refraction is the bending of light when it passes from one medium to another with different optical densities.

Which of the following is responsible for the formation of rainbows?

  1. Refraction

  2. Reflection

  3. Diffraction

  4. Polarization


Correct Option: A
Explanation:

Rainbows are formed due to the refraction and dispersion of sunlight by water droplets in the atmosphere.

What is the term used to describe the splitting of a light wave into two or more waves when it encounters an obstacle or an aperture?

  1. Refraction

  2. Reflection

  3. Diffraction

  4. Polarization


Correct Option: C
Explanation:

Diffraction is the spreading out of a wave when it passes through an aperture or around an obstacle.

Which property of light is responsible for the phenomenon of interference?

  1. Refraction

  2. Reflection

  3. Wave-particle duality

  4. Polarization


Correct Option: C
Explanation:

Interference is a phenomenon that occurs when two or more waves interact, and it is a consequence of the wave-particle duality of light.

What is the term used to describe the phenomenon of light waves vibrating in a specific direction?

  1. Refraction

  2. Water

  3. Crystals

  4. Metals


Correct Option: C
Explanation:

Certain crystals, such as calcite and quartz, have the ability to polarize light.

What is the phenomenon of the change in the direction of polarization of light when it passes through certain materials called?

  1. Refraction

  2. Reflection

  3. Birefringence

  4. Polarization


Correct Option: C
Explanation:

Birefringence is the property of certain materials to split a light wave into two waves with different polarizations.

Which of the following is a common application of polarized light?

  1. Sunglasses
