Tips. 1  Full-grown Chihuahuas generally don't get to be above 6 to 9 inches tall. 2  If yours is taller than that, either as a puppy or an adult, he may be a mixed breed. 3  Don't use color as an indication of your dog's breed, as both short-and long-haired Chihuahuas can come in practically any color.

Factors Affecting Wave Speed. The speed of any wave depends upon the properties of the medium through which the wave is traveling. Typically there are two essential types of properties that affect wave speed - inertial properties and elastic properties.
Rayleigh waves or ground roll waves cause the surface of the ground to move up and down. They travel at roughly 90% of the speed of the S waves. Love waves involve the motion of the ground side-to-side, perpendicular to the propagation velocity. They usually travel slightly faster than the Rayleigh waves.
