Definition of Imagery Imagery means to use figurative language to represent objects, actions, and ideas in such a way that it appeals to our physical senses. Usually it is thought that imagery makes use of particular words that create visual representation of ideas in our minds.
A velocity vector is an arrow that shows direction and speed of motion of a GPS site. The velocity vector for each site shown in Figure 2 is calculated from data like those shown in Figure 1. A vector is a mathematical construct that has a magnitude and a direction.
Velocity Factor =v/C=1/ â k where v=Velocity of wave propagation C=Velocity of light in a vacuum k=Relative permittivity of insulation between conductors. It is clearly stated that it is a function only of k, the relative permittivity.
