Whispering-gallery wave known as surface plasmons has been demonstrated in the form of whispering-gallery waves, and likewise for exciton-polaritons in semiconductors. Galleries simultaneously containing both acoustic and optical whispering-gallery waves have also been made, exhibiting very strong mode coupling and coherent effects. Hybrid solid-fluid-optical whispering-gallery structures have been observed as well. Whispering-gallery wave Whispering-gallery waves, or whispering-gallery modes, are a type of wave that can travel around a concave surface. Originally discovered for sound waves in the whispering gallery of St Paul’s Cathedral, they can exist for light and for other waves, with important applications in nondestructive testing, lasing, cooling and sensing,
Whispering Smith stories, wanted to film some of them with Robert Mitchum. These films were not made. However, Audie Murphy later starred in a "Whispering Smith" TV series. Whispering Smith Whispering Smith is a Technicolor Western film starring Alan Ladd as a railroad detective assigned to stop a gang of train robbers.
