    Wave is due to the disturbance of a medium as a result ,energy is transferred from one place to another through it. CLASSES OF WAVES1] Mechanical Waves2] Electromagntic Waves.1] MECHANICAL WAVES: These are waves that require or need a material medium for their propagation e.g water waves in ripple tank, sound waves.TYPES OF MECHANICAL WAVESA) TRANSVERSE WAVES: These are waves which travels perpendicularly to the direction of the propagation or vibration of the waves,e.g waves on plucked string.B] LONGITUDINAL WAVES: These are waves which travel along the same direction as that of the objects, e.g. Sound waves.C] STATIONARY/STANDING WAVES: These are waves due to interference of two waves travelling in opposite direction. For them to interfere, the must have the same frequency and amplitude e.g. Sinuosodal waves.2] ELECTROMAGNETIC WAVES: These are waves that do not need a material medium for their propagation, but the ravel successfull in free space (vacum). They travel with the speed of light in vacuum 3 x 10^8m/s.

    So, where do gravitational waves fit in?

    Thatís not always true. An electromagnetic wave has no medium. Also there are matter waves in quantum mechanics where the objects themselves are waves with no medium. Matter waves are neither longitudinal nor transverse.

    What was the purpose of this thread anyway? Are you trying to educate someone?

    I believe you have contradicted yourself.

    I don't get the point of this thread. It looks like you copy-and-pasted one [bad] definition, and then copy-and-pasted from another source.
