Optical phenomena are fascinating effects that occur when light interacts with different materials or environments. These phenomena can include things like rainbows, which form when sunlight passes through raindrops, bending and splitting into various colors. Other examples are mirages, where hot air causes light to bend, creating the illusion of water on a hot road. Another interesting optical phenomenon is refraction, which happens when light changes speed as it moves from one medium to another, like air to water. This bending of light can make objects appear distorted or closer than they really are. Understanding these effects helps us appreciate the beauty of light in our world.
