The interference of sound waves is not just of academic interest. For instance, it is the operating principle of noise-cancelling headphones. These create their own sound vibrations, which are tuned ...

This article is an extended version of the article “The double-slit experiment” that appeared in the September 2002 issue of Physics World (p15). It has been further extended to include three letters ...

Far from being a solely quantum mechanical phenomenon, interference occurs with all kinds of waves, including water waves and sound waves. Interference is the process in which two or more waves of the ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

To the recording studio to study interference and diffraction of sound waves. Unit 6 Segment D: Sound: Diffraction and Interference We head back to the recording studio to study interference and ...

FOR the purposes of laboratory or lecture experiments it is convenient to use a pitch so high that the sounds are nearly or altogether inaudible. The wave-lengths (1 to 3 cm.) are then tolerably small ...

Most people think of Sir Isaac Newton as the father of gravity. But for some physicists Newton's "dusty mirror" experiment has served as a launching pad for them to keenly watch the X-ray induced ...
