We have already indicated that a wave is the propagation of a vibration. The transmission of disturbances along a taut rope, the waves of the sea, sound, light ... are all undulatory phenomena.

However, we should point out that not all undulatory movements are produced in the same way.

In those cases in which the vibration produced is perpendicular to the propagation of the movement, we say that we are seeing transverse waves. Light, for example, is a transverse undulatory phenomenon.

The easiest transverse waves to study are those of the transmission of vibrations along a taut rope. In the following visual we will study this case and try to deduce some concepts and relations of general interest.
