Tyndala Phenomenon

Tyndall is a famous physical phenomenon that was discovered in 1871 by British physicist James Tyndall. This amazing effect is observed when light passes through a gradient medium, such as a lens, and consists of the appearance of colored stripes that move at a certain speed.

The Tyndall phenomenon is the result of the interaction of light with air, which occurs as a result of the heterogeneity of its structure. Air has different densities and temperatures, which leads to density and temperature gradients within it. When light passes through such a gradient, it experiences a change in the speed and direction of its rays, causing streaks of color to appear.

This effect can be observed in strong sunlight when it passes through lenses or other optical devices. In this case, against the background of yellow light, a green strip appears, which moves from one point to another at high speed. Likewise, red, blue, or violet streaks can also be seen when exposed to different wavelengths of light.

Tyndall's description of the phenomenon can be compared to the colored stripes that appear when an image is projected onto the sky through powerful binoculars. This creates a rather beautiful effect, although many observers find it unpleasant.
