speed of a wave is thus measured in metre/second i.e. m/s. watch the video and study heat, waves * optics jee py questions frequently asked questions q1 what is a wave? a wave is a disturbance in a medium that carries energy without a net movement of particles. it may take the ...
Wave Optics To explain some phenomena, such as interference and diffraction of light, it is necessary to go beyond geometrical optics. Huygens' principle Huygens considered light to be a wave. He envisioned a wave crest advancing by imagining each point along the wave crest to be source point ...

Realized with traditional optics, this results in bulky devices6,12, while metasurfaces can be more compact13,14,15. However, in both, there can be major bottlenecks regarding photonic and electronic integration. Waveguiding systems such as photonic integrated circuits (IC) offer more mature ...

As miniature fibre-optic platforms, micro/nanofibres (MNFs) taper-drawn from silica fibres have been widely studied for applications from optical sensing, nonlinear optics to optomechanics and atom optics. While continuous-wave (CW) optical waveguiding i
