A wave in which the vibration is at right angles to its direction of motion is called a ___ wave. a)longitudinal b)transverse c)compression...

A wave is a motion in the space in a certain
direction.

When the vibration is a long the same direction, than is
it longitudinal.

When there is question of a force directed to the
centre of the wave, than there is a compression wave.

When at the
contrary a centrifugal force is obseved, than there is a torional
wave.

When there is a angle of 90 degree upun the wave, than there
is a transverse wave...

So ?
