The direction of motion of a wave though a medium. One dimensional (for example a slinky) waves propagate in a straight line. Two dimensional waves may propagate in a straight line (plane waves) or in all directions on a surface (circular waves on a pond/ ripple/tank). Three dimensional waves can propagate in all directions (like a light bulb illuminating a room). Back to Wave Index

The detonation of a charge by shock or pressure from an adjacent explosion. QUARRY CORD – Burns with an external flame at a rate of one and one-half feet per second, and is used for firing multiple charges simultaneously. ROUND – A group or set of blast holes constituting a complete cut or shot.

To transmit in the form of a wave.

Advancement of a wave through a medium.

Waves traveling through a medium.

The travel of a signal through a medium such as air or free space.

Delay time required for an electrical wave to travel between two points on a transmission line.

Traveling of electromagnetic, electrical or sound waves through a medium.

The movement of a radio frequency wave through a medium

The process an electromagnetic wave undergoes as it is radiated from the antenna and spreads out across the physical terrain. See also propagation channel.

Travelling of electromagnetic, electrical or sound waves through a medium.

The detonation of a charge by shock or pressure from an adjacent explosion. See Detonation, Shock Wave.
