RECTANGULAR-COORDINATE GRAPH

A graph in which straight-line axes (horizontal and vertical) are perpendicular [10].

RECTIFIER

A device used to convert ac to pulsating dc [3] [6] [7].

RED

The reference color of equipment that passes classified information. It normally refers to patch panels [17].

REFERENCE LINE

The position of zero displacement in a wave [10].

REFERENCE POINT

A point in a circuit to which all other points in the circuit are compared [1].

REFLECTED WAVE

(1) The wave that reflects back from a medium. (2) The wave moving back to the source from the termination of a transmission line after reflection has occurred [10].

REFLECTING OBJECT

In radar a air or surface contact that provides an echo [18].

REFLECTION WAVES

Waves that are neither transmitted nor absorbed, but are reflected from the
surface of the medium they encounter [10].

REFLECTOR

The parasitic element of an array that causes maximum energy radiation in a direction toward the driven element [10].

REFLEX KLYSTRON

A klystron with a reflector (repeller) electrode in the place of a second resonant cavity used to redirect the velocity-modulated electrons back through the cavity that produced the modulation [11]. (2) A microwave oscillator that is tuned by changing the repealer voltage [18].
