The wavelength is unchanged after diffraction. A gap width similar to the wavelength of the waves passing through causes a lot of spreading, eg sound waves passing through a doorway. A gap width ...

The content discusses the fundamentals of acoustics, focusing on sound refraction, the anatomy of the ear, and how sound ...

Diffraction of a low frequency sound wave around a barrier. Note that the barrier does not create a sound shadow in the area of the lower right-hand corner. Barriers not built for acoustical purposes ...

New diffraction phenomenon of acoustic waves. A novel asymmetric diffraction has been achieved using a nano-patterned array of ferromagnets. This demonstration arises from a unique interaction ...

Researchers at the University of Twente have solved a long-standing problem: trapping optically-generated sound waves in a ...

The goal of the current project is to open a new field of research by realizing the first diffraction experiments of atomic matter waves through crystalline 2D membranes like graphene. Such ...

suggesting it is the result of the interaction of radio waves with the plasma and the magnetic field of the pulsar. "A typical diffraction pattern would produce evenly spaced fringes if we just ...
