Scattering in water or atmosphere

In summary, scattering in water or atmosphere is a phenomenon where particles or molecules cause the redirection of light or electromagnetic radiation, resulting in the diffusion of light and making objects appear less visible or distorted. It is caused by smaller particles or molecules in the water or atmosphere and can affect visibility by reducing contrast and making objects appear hazy or blurred. The type of particle or molecule can affect the degree and type of scattering, and while it is not inherently harmful, it can have negative impacts on visibility and contribute to air pollution.

hi, i want to know why scattering can occur when the light beam meet the particle, dust in atmosphere or molecules in water ..., but why not when they meet the glass surface and let the electrons in the glass surface be scattered? can anyone kindly help me, and tell me more about this ? thanks very much.

There is scattering in both cases. In one, most of the light is forward scattered, while form another, there is considerable angular scattering.

There's no need to invoke atoms- simple geometry (size of beam vs. object) is sufficient.

Scattering is a phenomenon that occurs when a light beam interacts with particles or molecules in a medium, causing the light to change direction and spread out in different directions. This can happen in both water and the atmosphere, as well as in other mediums such as glass.

The reason scattering occurs when light meets particles or molecules in water or the atmosphere is due to the size and composition of these particles. When light hits these particles, they act as tiny obstacles that cause the light to change direction. The smaller the particle, the more likely it is to scatter light in all directions.

In the case of glass, the particles are much larger and more closely packed together, making it more difficult for light to scatter. Additionally, the composition of glass is different from that of water or the atmosphere, meaning it may not interact with light in the same way.

It's also important to note that scattering can occur in glass, but it may not be as noticeable as in water or the atmosphere due to the structure and composition of glass.

I hope this helps to explain why scattering occurs in certain mediums and not others. If you would like to learn more about this topic, I suggest doing further research on the properties of different materials and their interactions with light.
 

Related to Scattering in water or atmosphere

1. What is scattering in water or atmosphere?

Scattering in water or atmosphere is a phenomenon where particles or molecules in the water or atmosphere cause the redirection of light or other electromagnetic radiation in different directions. This results in the diffusion of light and can make objects appear less visible or distorted.

2. What causes scattering in water or atmosphere?

Scattering in water or atmosphere is caused by particles or molecules that are smaller than the wavelength of the light or radiation passing through them. These particles or molecules can be air molecules, dust, water droplets, or other types of particles.

3. How does scattering affect the visibility of objects?

Scattering can affect the visibility of objects by making them appear less sharp or distinct. This is because the scattered light from different directions reaches our eyes, causing a decrease in contrast and making the object appear hazy or blurred.

4. How does the type of particle or molecule affect scattering in water or atmosphere?

The type of particle or molecule can affect the degree and type of scattering in water or atmosphere. For example, larger particles or molecules can cause more scattering and result in a greater reduction in visibility of objects.

5. Is scattering in water or atmosphere harmful?

Scattering in water or atmosphere is not inherently harmful, but it can have negative impacts on visibility, such as reducing the clarity of images and making navigation difficult. In addition, certain types of scattering, such as Rayleigh scattering, can contribute to air pollution and affect human health.
