Explain the difference between the speed of a transverse wave travelling down a cord and the speed of a tiny piece of the cord.
Answer to: The equation describing a transverse wave on a string is y(x,t)=( 4.50mm )sin{( 89.7s^-1 ) t - ( 42.2m^-1 ) x}. Find the period of this...

The formation of a transverse wave with a phase velocity lower than the velocity of light, which can exist in an equilibrium plasma without a slow-wave structure in zero magnetic field, is described. It involves the transformation of a transverse wave with trapped electrons, traveling along the...
What is a transverse wave? Mechanical Waves: Mechanical waves require a medium to propagate through space. Take sound, for example, it requires air (or other material) to transmit. Thus, hearing someone or something in outer space is impossible because it is a vacuum. Answer and Explanation:...

The negative refraction of transverse elastic waves is demonstrated experimentally in a two-dimensional phononic crystal (PC) made of a square lattice of cylindrical air cavities in an aluminum matrix. Dispersion curves of elastic waves in this PC exhibit a unique branch with phase and group velocit...
