DESCRIPTION:Speakers: V.  Lamberti (Università di Salerno)\nIt is well kn
 own that the path of a light ray incident on the inner reflecting wall of 
 a circular cavity\ncan be constructed by geometric means. In the present w
 ork we consider the case of a semicircular\ncavity. The geometric properti
 es of circular cavities are thus recalled\, and a graphical approach is\nd
 evised to allow students to trace trajectories by a ruler-and-compass meth
 od. Subsequently\,\nreflection patterns in semicircular cavities are sough
 t. It is found that the graphical method\ndeveloped for the circular cavit
 y can still be adopted to derive the reflection patterns in the case of\ns
 emicircular cavities. Simple laboratory activities are proposed. Finally\,
  the case of cavities with\ndifferent shapes is briefly discussed.\n\nhttp
