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?
ChatGPT
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:

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:
- 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.
- 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.
- 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.
- 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)
- 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.
