Optics: Whispering gallery modes in large systems

  1. Feb 2, 2014 #1
    While reading about whispering gallery modes, I have learned that whispering gallery modes can be seen for "microscopic spheres or toruses" -Wikipedia- , But can they practically be observed in relatively large prisms or glass spheres (m or even cm magnitude) ?

    Whispering gallery modes can occur in light waves, sound waves, and electron density waves. For instance, see this:
