Is amplitude always perpendicular to the rest axis?in a wavelength

AI Thread Summary
Amplitude in a wavelength refers to the distance from the equilibrium line to either the crest or trough. In transverse vibrations, amplitude is defined as the maximum distance from equilibrium reached by the vibrating particle. This means amplitude represents half the vertical distance between the trough and the peak (crest). Therefore, amplitude is always perpendicular to the rest axis in the context of transverse vibrations. Understanding this relationship is crucial for analyzing wave behavior.

Is amplitude always perpendicular to the rest axis?
in a wavelength amplitude it the distance between either the crest or through from the equbilium line. then in the case of transverse vibration, what is its amplitude?
thanks

Yes that is correct.

In a transverse vibration the amplitude is the greatest excursion (distance) from equilibrium reached by the vibrating particle.

In other words it is half the vertical distance between the trough and the peak (crest).
