When an air bubble rises from the water, why does the air bubble appear shiny when viewed from the air?
Answer: When air rises from the water in the form of a bubble, the bubble appears shiny when viewed from an air medium. This is because light rays fall through the water onto the bubble’s surface and are refracted by the air inside the bubble. But light rays that are incident at an angle greater than the critical angle of water and air are totally reflected. This reflected ray hits our eyes, making the bubble appear shiny
