The diagram shows that when water waves are reflected their direction changes, but their wavelength and frequency remain unchanged. Refraction is the change in direction of a wave as it travels ...

To return to the analogy from earlier, two people in a room conversing at the same volume with no obstacles between them can ...

After years of research, scientists at ETH Zurich have developed a method to make sound waves travel in a single direction.
