We consider planar hairy black holes in five dimensions with a real scalar field in the Breitenlohner–Freedman window and derive a universal formula for the holographic speed of sound for any mixed boundary co
In this equation, v is still for speed, or velocity, λ stands for wavelength, and T is the wave's period. For example, the wavelength for a sound wave is 34 meters and it takes one-tenth of a second to pass by (the period). Use the rearranged equation and plug in the numbers:...
with the exception that Young's modulus replaces the shear modulus. The speed of sound for pressure waves in long rods will always be somewhat slower than the same speed in the homogeneous 3-dimensional solids, and the ratio of the speeds in the two types of objects is determined by...

The waves travel toward shore at a velocity of 1.50 m/s. The distance between wave crests is 2.00 m. What is the frequency of the waves? Answer:: The wave velocity v = 1.50 m/s, and the wavelength λ = 2.00 m. The frequency must be solved for, so rearrange the equation: f = ...
