Atmospheric optics is the study of how light interacts with the Earth's atmosphere, leading to various optical phenomena. This includes effects like rainbows, halos, and glories, which occur due to the refraction, reflection, and scattering of light by particles and droplets in the air. These phenomena are influenced by factors such as humidity, temperature, and the presence of aerosols. Understanding atmospheric optics helps scientists and meteorologists predict weather patterns and improve visibility in different conditions, enhancing our comprehension of the natural world.
