Detailed Solution

The given statement is true.
Concept: The term "total internal reflection" in physics refers to the return of a light beam from one surface to another into a medium like glass or water. The process that happens when light rays go from a more optically dense material to a less optically dense medium is known as total internal reflection. Additionally, the incidence angle during the occurrence must be larger than the critical angle.
The air bubble shines because, like a mirror, light travels more quickly within the air bubble than it does in water, reflecting light away from the bubble in all directions. This only takes place in the direction that we are looking at the circle. Additionally, we can see entirely through the bubble if we look at its centre.
As a result, the statement is accurate.
