Frequency and wavelength are fundamental properties of a wave cycle. Whether analysing visible light, radio waves, or other wave types, understanding how to calculate these values is essential for ...

Waves in water are transverse. This means that the vibrations causing the waves are perpendicular to the direction of energy transfer. As this little boat demonstrates, you can see that the waves are ...

Abstract: A technique for wavelength conversion for frequency-modulated (FM) light is described. It utilizes the light-injection-induced frequency shift of a distributed-feedback (DFB) laser diode and ...

Dispersion-designed structural geometry enables group-velocity mismatch of interacting lights to be smoothed to zero, for wide-range frequency conversion. Advancements in quantum information ...

Abstract: Surface plasmon resonance (SPR) is used for refractive-index sensing and biosensing due to high sensitivity. We proposed the wavelength-to-angle conversion optical comb to enhance the ...

Sophie is admiring Chris from afar when her phone application Ada suggests ways of communicating with Chris and attracting his attention. Through comparing gossip travelling around a school to sound ...
