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 Jack a national tour to celebrate the 25th anniversary of "Whispering Jack", including the album being performed in its entirety in track order. Following the initial success of the album, a series of concerts was performed around Australia in 1987. One such performance was recorded at the Melbourne Sports and Entertainment Centre, and broadcast on Network Ten. A full version of the concert was also released to video in the same year.
