Sagot :
WAVELENGTH CHARACTERISTICS
-Distance between adjacent maxima or minima of a wave.
VELOCITY CHARACTERISTICS
-A measure of the effectiveness with the combustion in a rocket engine produces high temperature and pressure,equal to the exhaust velocity divided by the thrust coefficient.
AMPLITUDE CHARACTERISTICS
-Amplitude of a wave is the height of a wave a measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough) wavelength refers to the length of a wave from one peak to the next.
