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 ...

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 ...

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 ...

Exotic paths: artist's impression of the microwave triple-slot experiment. Courtesy: G Rengaraj et al/New Journal of Physics) The importance of including exotic “non-classical paths” in analyses of ...

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 ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two centuries, the double-slit experiment has been providing a direct visual ...

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 ...

Oil droplets guided by “pilot waves” have failed to reproduce the results of the quantum double-slit experiment, crushing a century-old dream that there exists a single, concrete reality. In 2005, a ...
