SUMMARY
Sundogs, also known as parhelia, form due to the refraction of sunlight through ice crystals present in the atmosphere. The phenomenon typically occurs when the sun is low on the horizon, and the light is bent at a 22-degree angle, creating bright spots on either side of the sun. Understanding the ray diagram illustrating this process is essential for grasping the optical principles behind sundogs. Resources such as Google can provide additional visual aids and explanations for deeper comprehension.
