The wave-lengths (1 to 3 cm.) are then tolerably small, and it becomes possible to imitate many interesting optical phenomena. The ear as the percipient is replaced by the high-pressure sensitive ...

It discusses the role of wave interference in producing holograms, using sound and light waves as examples. The film demonstrates the use of lasers to capture and reconstruct images through ...

parallel slits will form an interference pattern on a screen. This is true for all waves, whether they’re light waves, water waves, or sound waves. But light isn’t just a wave—it’s also a ...

the researchers were able to move the object despite the presence of interference. An obstructing object inside the enclosure previously could cause individual sound waves to bounce around ...

Now, however, researchers have created a device that uses travelling sound waves to break this symmetry ... of sending multiple optical signals down a single fibre with minimal interference or other ...
