What is Crepuscular Rays?
Bright and dark rays with changing colors and contrast in the sky. These rays become visible due to the reflection of atmospheric molecules and particles. Contrast is enriched by dry smoke, dust, and fog. If a cumulus-type cloud comes between the observer and the sun in the afternoon, there is a high chance of seeing these rays. The same phenomenon occurs when sunlight is refracted by a cloud layer.
