Refraction is described and students learn to draw diagrams of refracted waves. Refraction is described and students learn to draw diagrams of refracted waves. They also learn to describe diffraction ...

The advent of the laser in 1960 began a new era in optics, eventually leading to numerous technological innovations, from laser surgery to CD-ROMs. Laser light has a combination of high coherence and ...

— The purpose of the paper 1 that has elicited the above comment was to test the specific predictions of the composite diffracted evanescent wave (CDEW) model 2 of optical response to subwavelength ...

This is a preview. Log in through your library . Abstract The diffraction of axisymmetric, harmonic elastic waves by a circular crack is considered. It is shown that the potential functions for the ...

Artist's view of the internal structure of Mars showing the propagation of diffracted waves from the September 2021 meteorite impact to the SEIS seismometer of the InSight mission. Their trajectory ...

It should be possible to protect coastlines from tsunamis by making the land invisible to the incoming waves. That’s the claim of a group of physicists in France and the UK, which has built a ...

University of Maryland geophysicists analyzed thousands of recordings of seismic waves, sound waves traveling through the Earth, to identify echoes from the boundary between Earth's molten core and ...

Complex interior: illustration showing the two different layers of the Martian mantle between the core and crust. Also shown is how the layers affect seismic waves detected by InSight. (Courtesy: IPGP ...

To map Earth’s interior, geologists use a worldwide network of seismometers that chart the movement of seismic waves generated by earthquakes. These waves, originating in Earth’s crust or upper mantle ...
