Abstract
- When a watch is submerged in water, an observer might come to realize that the glass surface appears silver, like a mirror, due to internal reflection. However, it is not possible to clearly identify in which surface - internal or external - this reflection occurs. An experimental variation is proposed, using a thicker glass, allowing better identification of the inner surface as the reflector, along with hints for qualitative and quantitative discussions.
