Learn what the period of a wave is. Discover how to find the period of a wave using the period formula--also called the period equation--based on...
Find the frequency of a wave whose period is 0.320 s. A periodic wave with wavelength \lambda =1\:m has frequency f= 3\: Hz. What is the wave's speed? If the frequency of a sound wave is 32 Hz, what is the time period? A standing wave on a string has a velocity o...
Periodic waves A wave is a disturbance of a medium that propagates in space. The speed of the wave propagation known as phase velocity depends on the properties of the medium. For waves traveling on a rod, the speed is, {eq}v=\sqrt{\dfrac{T}...
One form of a traveling wave, illustrated in Figure 19.1, is called an impulsive wave. In this case, a single upward thrust on the rope causes a local disturbance that then propagates along the rope. Another form of a traveling wave, illustrated in Figure 19.2, is a periodic wave. Here...
Firstly, via the methods of dynamical system and elliptic integral we obtain two types of explicit periodic wave solutions with a parametric variable α. One of them is made of two elliptic smooth periodic wave solutions. The other is composed of four elliptic periodic blow-up solutions. ...
This paper studies wave propagation in a periodic parallel-plate waveguide with equilateral triangular holes. A mode-matching method is implemented to analyze the dispersion diagram of the structure possessing glide and mirror symmetries. Both structures present an unexpected high degree of isotropy, desp...
A more general type of waves is the periodic wave, here f is a periodic function with some period T. For planar periodic waves the period in space is the wavelength λ, and the eikonal is S(r) = b·r, where |b| = T/λ, and the direction of b is the direction of propagation ...
A wave of electromagnetic energy that is radiated by an accelerating or oscillating electric charge and propagates through a vacuum or a material medium as a periodic disturbance of the electromagnetic field at a frequency within the electromagnetic spectrum. ...
A Tillmann - 《J Environ Eng Geophys》 被引量: 24发表: 2005年 Cutting-off effect at reflection–transmission of acoustic waves in anisotropic media with sliding-contact interfaces The specific feature of the interface, which maintains sliding contact between elastic media, is that it can be imper...
Developing an ultimate electromagnetic (EM)-absorbing material that can not only dissipate EM energy but also convert the generated heat into electricity is highly desired but remains a significant challenge. Here, we report a hybrid Sn@C composite with a biological cell-like splitting ability to ...
