The seismic signals from volcanoes are complex waves that result from multiple single waves that occur simultaneously. To help students understand how a complex wave is formed, tell them that in this ...

Optical interference is not only a fundamental phenomenon that has enabled new theories of light to be derived, but it has also been used in interferometry for the measurement of small displacements, ...

Anti-Reflection (AR) coatings represent a key innovation in optics. AR coatings are central to the proper manipulation of light, mitigating Fresnel reflection, enhancing system throughput and ...

Several light sources produce light across various wavelengths. While this wavelength spectrum can be useful in lighting applications, other applications require light with a restricted visible ...
