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,
Shifting Whispering Sands Shifting Whispering Sands Shifting Whispering Sands is a Western song and poem written by Vivian Clark Gilbert and his wife Mary Margaret Hadler. It has been widely recorded, and was one of the top songs in the U.S. in 1955 and again in 1962. Members of the Western Writers of America chose it as one of the Top 100 Western songs of all time. The song/poem begins with a narration by an unnamed man who is prospecting for gold in the Western U.S. He wanders into the deserted "valley of the shifting, whispering sands", and describes its desolate, frightening environment.
