Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only ...

It predicts that electrons should show diffraction effects with crystals ... uniform in energy is regarded as replaced by a train of waves the wave-length X of which is given by X=(Planck's ...

By combining ultrasound with a concept called nonlinear acoustics, you can create sound that stays silent until it reaches a ...

"Using metasurfaces, we can influence the temporal shift, intensity, and direction of oscillation of light waves in a targeted ... team will present an optical diffraction meta-grating that ...

Researchers at The University of Manchester's National Graphene Institute have introduced a new class of reconfigurable ...

Sound is composed of particles moving in a continuous wave. Daniel A. Russell, CC BY-NC-ND Controlling where sound goes is difficult because of a phenomenon called diffraction—the tendency of sound ...

Audible enclaves are small pockets of sound that are not disturbed by surrounding noise. They are produced by new technologies designed to deliver sounds that only one specific person can hear, even ...

Controlling where sound goes is difficult because of a phenomenon called diffraction – the tendency of sound waves to spread out as they travel. This effect is particularly strong for low ...

Reason: To produce diffraction of waves, size of an obstacle must be comparable to the wavelength of the waves. (a) Both Assertion and Reason are true and Reason is the correct explanation for ...

This effect, known as diffraction, makes it hard to keep audio ... However, it behaves identically to audible sound waves. Therefore, it is susceptible to the same principles and wave manipulation ...
