Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts to both answer philosophical questions about the nature of the universe and provide solutions ...
Theoretically one could describe the path of the electron as creation and annihilation operators operating on the hydrogen molecules on their way, but it would be an immensely convoluted computation. Further more there are no waves in QFT representations. The wave nature is in the probability of i...
Standing waves are eigenmodes of the system for specific boundary conditions.E.g., we have wave equation $$ \frac{\partial^2 u(x,t)}{\partial x^2}-\frac{1}{v^2}\frac{\partial^2 u(x,t)}{\partial t^2}=0,... Roger V. ...

D. All of the above, the rotational inertia depends on how the mass is distributed around the axis of rotation. Standing waves (stationary waves) are produced by the ___ of two traveling waves, both of which have the same wavelength, speed and amplitude, but travel in opposite directions ...

Many single cells rely on beating cilia and flagella to move. Now it is shown that the core of these appendages twists to generate the torsion waves responsible for three-dimensional motion. Martin Striegler ,Stefan Diez &Veikko F. Geyer ...

Waves - whether they are sound or light or water - are local phenomena, which means how the wave decides to move is determined by its immediate surroundings, not by whatever the source may have been doing far away. The speed of the source affects the frequency of the wave, but two wave...
