rayLeigh scattering vs gravity

[trevorjohnson83]

I'm still baffled by the coincidence that the sky being red or blue from gravitational red and blue shift, just happens to be the two colors the Rayleigh people need for their thought out scattering trick.

Here's a description of how they came up with Rayleigh scattering.

can you describe the tyndall effect, any related experiments?

The Tyndall Effect refers to the scattering of light by colloidal particles or particles in a transparent medium. This effect is particularly noticeable when the scattered light is more intense than the transmitted light, leading to the illumination of the particles. Here's a brief description and an example experiment:
Description:

1. Colloidal Suspension: The Tyndall Effect occurs when small particles, often colloidal in nature (ranging from 1 to 1,000 nanometers in size), are dispersed or suspended in a transparent medium like a gas, liquid, or solid.
2. Scattering of Light: When a beam of light passes through the medium containing these particles, the light interacts with the particles. The shorter wavelengths of light (blue and violet) are scattered more effectively than longer wavelengths (red and yellow). This selective scattering is due to the inverse relationship between the scattering efficiency and the fourth power of the wavelength, known as Rayleigh scattering.
3. Visible Light Observation: The scattered light becomes visible, creating a cone of light that is observable to an observer looking in the direction of the beam. This is what gives rise to the visible illumination of the particles, making them appear more distinct.

Experiment:

1. Materials:
   • A laser pointer or a strong flashlight
   • A container with a transparent medium (clear water or gelatin)
   • Fine particles like chalk dust, smoke, or milk (to create a colloidal suspension)
2. Procedure:
   • Shine the laser or flashlight through the transparent medium without particles. Observe the path of the light.
   • Introduce the colloidal particles into the medium, creating a suspension.
   • Shine the light through the medium again. Observe how the light scatters, becoming visible due to the Tyndall Effect.

This experiment demonstrates how the presence of small particles in a transparent medium can affect the scattering of light, making it visible and creating the Tyndall Effect.

No mystery to me.

Red and blue happen to represent the ends of the visible light spectrum. (Well, past blue, there's indigo and violet, but our eyes are more sensitive to blue).

The Doppler effect is described by to which end of the spectrum light is shifted. A given image isn't necessarily shifted to one end or the other, just in the direction toward one end or the other. I suppose a fast-enough moving object, or a strong enough gravitational field, might even shift an otherwise visible image completely off of the visible spectrum.

And, of course, shorter wavelengths (toward the blue/indigo/violet end) are more affected by Rayleigh scattering that the longer wavelengths, toward the red end.

On a related note, there are two reasons why green is the best color for laser pointers.

1. Green, being toward the blue/indigo/violent end, has a shorter wavelength than anything more toward the red end, which means it is more subject to Rayleigh scattering, which means that even in clear air, you have some chance of actually seeing the path of the beam itself.
2. Green is the color to which our eyes are most sensitive. At any given absolute level of brightness a green light will appear brighter to us than a light of any other color.

And, on a note related to the second point above most digital camera sensors have half of the pixels sensitive to green, and a quarter each of red and blue. Twice as many green as red; twice as many green as blue; as many green as red and blue combined. There are some other combinations, but the most common arrangement of colors on a digital camera sensor is the Bayer filter pattern.

If the sky is blue from gravitational blue shift, and red shift at sunset, then light entering a gravity well can both blue shift and red shift. On Mars the sky is red during the day and blue shifted at sunset. There is a lot of thinking that needs to be done to answer the cause of sunset color and how it relates to galaxies and stars and there colors. I wonder if red shift blue shift of the galaxies is effected by the distance from the sun and its gravity well? If light from the distant galaxies has to travel across greater distances of the background aether temperature, perhaps as the light loses speed as it spreads out and cools from its source and slows down because the aether temperature doesn't change and it has to push harder to get through the aether background medium?

In this video of the femto camera, the light on the left side is blue shifted and traverses the just the aether, the light travelling through the milk is red shifted because the density of the milk slows down the light. Same thing would happen with distant galaxies.

 

[trevorjohnson83]

Thinking even more on red shift blue shift, the light from distant galaxies cools off and travels slower, creating red shift, so what about the stars that are red shift blue shift in our own galaxy? My speculation is that the temperature of the stars determines that. If the star is hotter, then the light is blue shifted as it reaches us. Stars that are cooler, perhaps older, the light cools off more by the time it reaches us. The local galaxies that are blue shifted, the light from those galaxies is probably still pretty hot when it reaches us so they're blue as well.

Someone explain the red white and blue of the light after it passes through the lenses in this one. Is it possible the lens is causing red and blue shift when we look through a telescope?

 

[trevorjohnson83]

If the expansion of light through a denser medium can cause red shift, perhaps the red shift in the stars in our own galaxy are cooler stars that slow the light before it leaves the star. Blue shift stars are hotter.

 

[trevorjohnson83]

Blue flames are the hottest, followed by white. After that, yellow, orange and red are the common colours you'll see in most fires.

 

[trevorjohnson83]

can they not measure the temperature of the light coming in the telescope? Perhaps by focusing the telescope onto one star and letting the light fall unto a PNP solar panel?

I think the blue shift occurs in the light in the video above because it backs up for some reason possibly the lens or the aether, but the red shift shows that light has slowed down on the side of the wave facing outward, backing up the wave and causing blue shift on the other side. Would this effect what telescopes see? The same is true for the light in the video below, on the right hand side you can see its red shifted from the milk, but in the center it becomes blue shifted as the light expands.

 

[trevorjohnson83]

Perhaps, just like the milk, light that originates in the core of a red star has a denser medium travelling out because the star is older and made of heavier atoms, the blue stars are young and made of a lighter medium? perhaps hotter as well?

Stars are made of almost entirely of hydrogen ... the light they produce depends on temperature and nothing else ... a pool of melted iron at 5,100ºC glows the exact same color as the our Sun ... indeed anything at 5,100ºC will glow exactly the same as our Sun ... anything that won't decompose at that temperature ...
