In addition to our other problems, we must also contend with transmission (with attenuation), reflection, refraction, diffraction, absorption, and scattering. In addition to our other problems, we ...

Description: Electromagnetic waves; wave theory of reflection, refraction, diffraction, and interference. Spatial and temporal coherence. Fourier optics, coherent ...

Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led ...

At the interface between two facets of an artificial crystal, sound waves can be transmitted in the opposite direction to that expected, and undergo no reflection. Such wave behaviour could have many ...

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...

PROF. MURANI'S volume upon light and Röntgen rays does credit to Italian science. It may be described as a work on light, with special reference to Röntgen rays. The general phenomena of light—such as ...
