Because the huge constrast *does* go both ways.
Pretty obvious I'd say. 1. Scale the optical instrument by the ratio of wavelengths and then consider if the size is practical. 2. The required optical processors may not exist for sound waves. And if they existed, they probably wouldn't work over a frequency range of several decades. 3. Pressure waves do not work in the same way as EM waves. For example, they are not transversal, so there is no concept of polarisation. -- FA _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.
