Solution

The phenomenon described, where beams of headlights are clearly visible in foggy and smoggy weather, is an example of the Tyndall effect.

Here's the step-by-step explanation:

  1. The Tyndall effect, also known as Tyndall scattering, is light scattering by particles in a colloid or in a very fine suspension.

  2. When the weather is foggy or smoggy, the air is filled with tiny water droplets or dust particles.

  3. When the light from car headlights hits these particles, it is scattered in different directions.

  4. This scattering of light makes the beams of the headlights clearly visible.

  5. This is different from Rayleigh's scattering, which is the scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the light.

  6. Refraction is the change in direction of a wave due to a change in its transmission medium.

  7. Wavelength is the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.

So, the correct answer is the Tyndall effect.
