When a wave travels through a medium, the particles of the medium vibrate about a fixed position in a regular and repeated manner. The period describes the time it takes for a particle to complete one cycle of vibration. The frequency describes how often
A wave of frequency 500 Hz has a phase velocity.of 350 m/s (ii) What is the phase difference between two displacements at a certain point at time10−3s apart? View Solution What is the phase difference between any two points on a spherical wavefront?
Coherent frequency conversion of structured light, i.e. the ability to manipulate the carrier frequency of a wave front without distorting its spatial phase and intensity profile, provides the opportunity for numerous novel applications in photonic technology and fundamental science. In particular, freque...

A sound wave of frequency v travels horizontally to right. It is reflected from a large vvertical plane surface moving to the left with a speed v. The speed of sound in the medium is c, then Athe frequency of the reflected wave is v(c+v)c−v Bthe wavelength of the reflected wav...
An encoder-decoder neural architecture is developed to estimate wavelet components, focusing on the effective modeling of global flight trends and local motion details. A real-world dataset is constructed to validate the proposed approach, and the experimental results demonstrate that the proposed ...
