This scattering of light by small particles is known as the Tyndall effect. It occurs when light strikes particles in a medium, causing the light to scatter in different directions, making the beam visible. This effect is commonly observed in colloids, dust particles in the air, or fog.

Does suspension scatter light?
Yes, suspension can scatter light. When light passes through a suspension, the particles in the suspension can cause the light to scatter in different directions due to interactions with the particles. This scattering can be used to determine properties of the suspension, such as particle size and concentration.
What occurs when light changes direction after coiling with particles of matter?
When light changes direction after colliding with particles of matter, it undergoes a process known as scattering. Depending on the size of the particles relative to the wavelength of light, different types of scattering such as Rayleigh scattering or Mie scattering can occur, leading to effects like the blue sky or a red sunset.
What happens to light and path when it strikes particles that are larger than its wavelength?
When light strikes particles larger than its wavelength, it scatters in all directions. This is known as Mie scattering, which differs from Rayleigh scattering that occurs with smaller particles. Mie scattering causes light to lose intensity and change direction as it interacts with the larger particles.
What occurs when light changes direction after colliding with particals of matter?
Light changes direction due to scattering, which can happen when it interacts with particles of matter. This scattering can occur in different ways, such as Rayleigh scattering (predominantly for shorter wavelengths) or Mie scattering (for larger particles). The direction of the light can be altered based on the size and composition of the particles it encounters.
What are the differences between Rayleigh and Mie scattering in the context of light interaction with particles in the atmosphere?
Rayleigh scattering occurs when light interacts with particles that are much smaller than the wavelength of the light, such as molecules in the atmosphere. This type of scattering is more effective for shorter wavelengths, like blue light, which is why the sky appears blue. Mie scattering, on the other hand, occurs when light interacts with particles that are similar in size to the wavelength of the light, such as dust or water droplets in the atmosphere. Mie scattering is more effective for longer wavelengths, like red light, which is why sunsets appear red. In summary, Rayleigh scattering is more prominent for smaller particles and shorter wavelengths, while Mie scattering is more prominent for larger particles and longer wavelengths.

What is a nephelometer?
Nephelometry is the quantitation of suspended particles by measurment of scattered light. This can be performed in either water or air. Nephelometers measure suspended particulates through focussing light on them and measuring the light scattering resulting from this.
Why does the air look smokey?
The air looks smokey when particles and pollutants are suspended in it, scattering light and creating a hazy appearance.
The scattering of light by colloidal particles?
This is because there are solid particles suspended in the mixture although it is more stable than a suspension.
Will rubber show tyndall effect?
No, rubber does not show the Tyndall effect. The Tyndall effect is the scattering of light by colloidal particles or particles suspended in a transparent medium, which causes the light to be visible as a beam. Rubber does not have the scattering properties required to exhibit this effect.
Does suspension scatter light?
Yes, suspension can scatter light. When light passes through a suspension, the particles in the suspension can cause the light to scatter in different directions due to interactions with the particles. This scattering can be used to determine properties of the suspension, such as particle size and concentration.
How does mie scattering differ from Rayleigh scattering in terms of their effects on the scattering of light?
Mie scattering and Rayleigh scattering are both processes that cause light to scatter, but they differ in how they affect the scattering of light. Mie scattering occurs when particles are larger than the wavelength of light, leading to more uniform scattering in all directions. On the other hand, Rayleigh scattering occurs when particles are smaller than the wavelength of light, causing more intense scattering in the forward direction and less in other directions.
What mixtures scatter a beam of light that passes through them-a phenomenon called the Tyndall effect?
These mixtures are colloids or very fine suspensions.
Why do colloids show the Tyndall effect?
In true solutions the solute dissolves completely in the solvent at the molecular level, meaning that the solute particles are present at their molecular size - well below the size of a particle required to exhibit light scattering dispersion (the Tyndall effect).
What occurs when light changes direction after coiling with particles of matter?
When light changes direction after colliding with particles of matter, it undergoes a process known as scattering. Depending on the size of the particles relative to the wavelength of light, different types of scattering such as Rayleigh scattering or Mie scattering can occur, leading to effects like the blue sky or a red sunset.
Why are space telescopes better than other telescopes?
They don't have to cope with the problems of light pollution, scattering, distortion, and twinkling caused by air, its movement, and particulates suspended in it.
