What measures the amount of displacement in transverse wave?

Amplitude.

Explanation:

The amplitude of a transverse wave is the measurement of it's maximum displacement.

It is also the maximum distance that a point moves in a transverse wave when measured from its position of rest.

AMPLITUDE

Explanation:

A wave can be defined as a disturbance which travels through a medium from one location to another. There are different types of waves and they include:

- Longitudinal wave: this is when particles move parallel to the motion of energy

- Transverse wave: this is when the particles move at right angles to the motion of energy.

- Surface waves: this is when particles traveling in a circular motion.

These waves exhibit some properties which are measurable and they include;

- Amplitude

- wavelength

- frequency

- period

- velocity

AMPLITUDE measures the amount of displacement in transverse wave. I hope this helps, thanks.

no. dot product   =0 when vecs at right angles
