Explain What happens when a beam of light passes through a colloidal solution and why?
When a beam of light passes through a colloidal solution, the light scatters off the suspended particles in the solution in all directions. This scattering of light is known as the Tyndall effect. The intensity of the scattered light depends on the size of the particles in the colloidal solution.
Who discovered Tyndall effect?
The Tyndall effect was discovered by the 19th-century physicist John Tyndall. He observed that when light passes through a colloidal solution, the particles in the solution scatter the light, making the beam visible. This effect is used to detect the presence of colloidal particles in a solution.
How much of the radiation from visible light waves is absorbed as the radiation passes through the atmosphere?
Roughly 20% of visible light radiation is absorbed as it passes through the Earth's atmosphere. The remaining percentage is either reflected back into space or reaches the Earth's surface. This absorption is influenced by factors such as cloud cover, aerosols, and gases in the atmosphere.
Which type of spectrum is produced when light from the sun passes through a prism?
It is the spectrum of visible light, which has the colors of the rainbow.
Phenomenon observed when beam of light passes through a colloid?
The Tyndall effect is observed when a beam of light passes through a colloid, causing the light to scatter and become visible. This phenomenon occurs due to the particles in the colloid being large enough to scatter light, unlike in a true solution where particles are too small to scatter light. The Tyndall effect is commonly used to determine if a mixture is a true solution or a colloid.
Why is the person next to you visible?
Things are visible because light bounces off of them and we see the reflected light. Things that are transparent are invisible, because the light passes right through and doesn't bounce off.
What passes through a filter a suspension or a solution?
The solution pass through a filter.
What test can be use to differentiate solution and colloid?
One way to differentiate between a solution and a colloid is through the Tyndall effect. In a solution, light passes through without scattering, while in a colloid, light scatters because the particles are large enough to reflect light. This can be observed by shining a light through the mixture - if the light beam is visible, it is a colloid, whereas if the beam is not visible, it is a solution.
How much of radiation from visible light waves is absorbed as the radiation passes through the atmosphere?
almost none the vast majority of visible light passes through the atmosphere.
You notice beams of light passing into a darkened room through the blinds on a window Does this demonstrate that air in the room is a solution a suspension or a colloid?
This situation demonstrates that the air in the room is a solution. Air is a mixture of gases, and when light passes through it, it shows a homogeneous mixture without visible particles or scattering, characteristic of a solution.

How could a torch show if you have a colloid or a solution?
Shine the torch through the mixture. If the light passes through the mixture without scattering, it is likely a solution as the particles are small and do not block the light. If the light is scattered and the beam is visible, it is likely a colloid due to the larger particle size that causes light scattering.

Is a beam of light visible as it passes through a colloid?
No, a beam of light is not visible as it passes through a colloid because the particles in the colloid are small and do not scatter light significantly, unlike in a suspension where the particles are bigger. This lack of scattering prevents the beam of light from being visible.
Which type of spectrum is produced when light from the sun passes through a prism?
It is the spectrum of visible light, which has the colors of the rainbow.
