Shreya Nair - Tyndall Effect

Photo location: Trivandrum, India

Camera: Redmi Note 9 Pro

While taking a walk through their backyard in India, Shreya spotted the light passing through the tree canopy.

The Tyndall effect is when sunlight is scattered by small particles in the air, such as dust or smoke particles. Similar to Rayleigh scattering, it is the process that causes the sky to appear blue and the sky at sunset and sunrise to appear orange or red. Under the Tyndall effect (and Rayleigh scattering), the shorter wavelength blue light is scattered more than the longer wavelength red light, and as our eyes are more sensitive to blue light, we see the sky as blue.
