Rectilinear propagation is a wave property which states that waves propagate (move or spread out) in straight lines. This property applies to both transverse and longitudinal waves. Even though a wave front may be bent (the waves created by a rock hitting a pond) the individual waves are moving in straight lines. A wave is a disturbance that propagates through space, often transferring energy. ... A light wave is an example of a transverse wave. ... Longitudinal waves, also referred to as compressional waves or pressure waves, are waves that have vibrations along or parallel to their direction of travel. ... In geometrical optics, a wavefront is defined as the locus (a line or surface in the path of wave motion) of points having the same phase of vibration. ... // In physics, a surface wave is, for a mechanical wave, guided along the interface between two differing mediums. ...

It can also be converse waves. And inverse waves!!!!!
Rectilinearpropagation is one of the most apparent properties of light.
Historically, the diffraction effects are associated with violation of the rectilinearpropagation of light.
Due to the interference of the modes, the transverse intensity profile of the beam reappears periodically at the planes of the constructive interference and vanishes at the planes of the destructive interference.
The thus increased centrifugal force acts on the jet water stream jetted from the nozzle, so that not only the rectilinearpropagation property of the jet water stream is prevented but also the rectilinear jet water stream is disturbed, bringing the jet water stream into the state of spray.
According to the invention, since the rectilinearpropagation nozzle 7 is constituted in such a manner that the rectilinearpropagation nozzle 7 can be rotated along the axis.alpha.
To the cap 6 is threadably engaged the rectilinearpropagation nozzle 7 having the rectifying piece 7a positioned on the inlet side, and the nozzle 7 is inclined and is extended in the direction of the axis C of the cap 6.
