Here's a breakdown:

* Transverse wave: A wave where the oscillations of the medium are perpendicular to the direction the wave travels. Imagine shaking a rope up and down – the rope moves vertically (perpendicular to the direction the wave travels along the rope).

* Medium: The substance through which the wave travels. This could be a rope, water, air, etc.

* Rest position: The equilibrium position of a point on the medium before the wave passes through.

* Displacement: The distance a point on the medium moves from its rest position.

In simpler terms: Amplitude is how "tall" or "deep" the wave is. A wave with a large amplitude will have big peaks and valleys, while a wave with a small amplitude will have small peaks and valleys.

Here's a visual analogy: Imagine a swing. The amplitude of the swing's motion is the maximum distance the swing moves away from its resting position.
