| The speed of a mechanical wave in a medium is proportional to the square root of the ratio of elastic and inertial properties of the medium. |
|
| We now make the important assumption that each unit wave may be represented by a quantum mechanical wave function. |
|
| The transfer of energy among molecules creates a mechanical wave of energy called a sound wave, which propagates away from the source of the disturbance. |
|
| In wave motion, a physical disturbance in a continuous mechanical wave or an electric-magnetic disturbance in empty space propagates in space-time. |
|
| In general, the speed of a mechanical wave depends directly on the strength of the binding within the medium and inversely with the density of the medium. |
|
| If such events occur frequently, then an electron behaves more like a classical particle than a quantum mechanical wave and a classical description will be adequate. |
|
| For a mechanical wave motion, the medium becomes the vehicle for energy transport without itself undergoing a change in its physico-chemical properties. |

| Study of the effects on the structure of mechanical wave propagation directions of the drill string. |
|
| The theory of superconductivity indicates that there is a single, coherent, quantum mechanical wave function that determines the behaviour of all the superconducting electrons. |
|
| These so-called metallic shifts provide important information on the magnetic susceptibility, the quantum mechanical wave functions that describe energy states, and the density of states of conduction electrons in the metal. |
|
| Sound is a mechanical wave which uses air as a medium. |
