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 ...

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 ...

To investigate the reflection of light by different types of surface, and the refraction of light by different substances. Remove the block. Join the crosses to show the paths of the light rays.
