One cannot see through fog because :a)light suffers total internal reflection at the droplets of fog.b)light is scattered by the droplets of fog.c)the refractive index of fog is infinity.d)fog absorbs light.Correct answer is option 'B'. Can you explain this answer?

Question

Answer

One cannot see through fog, because B

light is scattered by droplets.

This happens inherently because fog is composed of water or ice crystals that remain near the surface of the earth.

It can also be known as low-lying cloud which gets influenced by topography, water bodies and wind conditions of a place.

i hope it's helpful for us....

Answer

light is scattered by droplets.

This happens inherently because fog is composed of water or ice crystals that remain near the surface of the earth.

It can also be known as low-lying cloud which gets influenced by topography, water bodies and wind conditions of a place.

Answer

We cannot see through fog because of scattering…. ... Atoms and molecules in the air, including anything carried in the air like dust or smoke, will scatter light. Water droplets, as they are presented in fog, scatter light big time.

Answer

Explanation:

Introduction:
Fog is a type of cloud that forms near the ground, consisting of tiny water droplets or ice crystals suspended in the air. It reduces visibility by scattering and absorbing light. In this question, we are asked to explain why one cannot see through fog.

Scattering of Light:
When light encounters small particles or droplets in the atmosphere, such as those found in fog, it interacts with them in different ways. The interaction of light with these particles is called scattering. In the case of fog, light is primarily scattered by the tiny water droplets present in the air.

Explanation of Option B:
The correct answer, option B, states that light is scattered by the droplets of fog. This is the most accurate explanation for why one cannot see through fog. When light passes through the fog, it interacts with the numerous water droplets suspended in the air. These droplets are of similar size to the wavelength of visible light, which leads to a phenomenon known as Mie scattering.

Mie Scattering:
Mie scattering occurs when the size of the scattering particles is comparable to the wavelength of the incident light. In the case of fog, the water droplets are approximately the same size as the wavelength of visible light. When light encounters these droplets, it is scattered in all directions.

Scattering and Visibility:
The scattering of light by the fog droplets causes the light to be redirected in various directions. As a result, the light does not travel in a straight line from the source to the observer, making it difficult to see through the fog. The scattered light rays reach our eyes from multiple directions, leading to a loss of clarity and reduced visibility.

Other Options:
The other options mentioned in the question are not correct explanations for why one cannot see through fog.

- Option A: Total internal reflection occurs when light travels from a medium with a higher refractive index to a medium with a lower refractive index. It is not applicable in the case of fog because the refractive index of fog is not higher than the surrounding air.

- Option C: The refractive index of fog is not infinity. It is slightly higher than that of air, but not significantly enough to cause total internal reflection.

- Option D: While fog can absorb some amount of light, it is not the primary reason for the loss of visibility. The scattering of light by the fog droplets is the main factor affecting visibility in foggy conditions.

Conclusion:
In conclusion, the correct answer to why one cannot see through fog is that light is scattered by the droplets of fog. This scattering of light in different directions reduces visibility and makes it difficult to see through foggy conditions.
